description: Evidence from pulsar wind nebula symmetry axes and radio polarization observations suggests that pulsar motions correlate with the spin directions. We assemble this evidence for young isolated pulsars and show how it can be used to quantitatively constrain birth kick scenarios. We illustrate by computing several plausible, but idealized, models where the momentum thrust is proportional to the neutrino cooling luminosity of the proto-neutron star. Our kick simulations include the effects of pulsar acceleration and spin-up and our maximum likelihood comparison with the data constrains the model parameters. The fit to the pulsar spin and velocity measurements suggests that: i) the anisotropic momentum required amounts to ~10% of the neutrino flux, ii) while a pre-kick spin of the star is required, the preferred magnitude is small 10-20rad/s, so that for the best-fit models iii) the bulk of the spin is kick-induced with $\bar Ω$ ~120rad/s and iv) the models suggest that the anisotropy emerges on a timescale $τ$ ~1-3s.

description: The scope of this thesis is to investigate the failure mechanisms of the coastal zones’ slopes of Pantocratora's Holy Monastery on Mount Athos, using the LIDAR device for the 3D mapping of the structures of the rock mass. The fieldwork prior of implementation of the LIDAR methodology included the study of the area's overall geomorphology and especially the orientation of the slopes and of the tectonic structures, the geology of the main formations and also information about their stage of weathering, stratification etc. Also the mechanical characteristics of the discontinuities have been estimated via in situ tests.Subsequently all slopes were scanned by LIDAR device in order to capture their structure and tectonic diagrams were produced in correlation with data of fieldwork and LIDAR technique for two of the slopes in the area mentioned above. Kinematic analysis was carried out for the estimation of all potential failures. Slope stability included the calculation of safety factors for every potential failure mechanism, based on the results of both methods.The conclusions include remedial measures for the potential failures and for the overall condition of the area. Furthermore, the thesis results discuss the applicability and reliability of the technique for the investigation of slope failure mechanisms via the LIDAR scanning method in conjunction with field data.

description: Learning from streaming tasks leads a model to catastrophically erase unique experiences it absorbs from previous episodes. While regularization techniques such as LWF, SI, EWC have proven themselves as an effective avenue to overcome this issue by constraining important parameters of old tasks from changing when accepting new concepts, these approaches do not exploit common information of each task which can be shared to existing neurons. As a result, they do not scale well to large-scale problems since the parameter importance variables quickly explode. An Inter-Task Synaptic Mapping (ISYANA) is proposed here to underpin knowledge retention for continual learning. ISYANA combines task-to-neuron relationship as well as concept-to-concept relationship such that it prevents a neuron to embrace distinct concepts while merely accepting relevant concept. Numerical study in the benchmark continual learning problems has been carried out followed by comparison against prominent continual learning algorithms. ISYANA exhibits competitive performance compared to state of the arts. Codes of ISYANA is made available in \url{https://github.com/ContinualAL/ISYANAKBS}.

description: We present a search for CO(1->0) emission in three Local Group dwarf irregular galaxies: IC5152, the Phoenix dwarf, and UGCA438, using the ATNF Mopra radio telescope. Our scans largely cover the optical extent of the galaxies and the stripped HI cloud West of the Phoenix dwarf. Apart from a tentative but non-significant emission peak at one position in the Phoenix dwarf, no significant emission was detected in the CO spectra of these galaxies. For a velocity width of 6 km/s, we derive 4sigma upper limits of 0.03 K km/s, 0.04 K km/s and 0.06 K km/s for IC5152, the Phoenix dwarf and UGCA438, respectively. This is an improvement of over a factor of 10 compared with previous observations of IC5152; the other two galaxies had not yet been observed at millimeter wavelengths. Assuming a Galactic CO-to-H_2 conversion factor, we derive upper limits on the molecular gas mass of 6.2 x 10^4 M_sun, 3.7 x 10^3 M_sun and 1.4 x 10^5 M_sun for IC5152, the Phoenix dwarf and UGCA438, respectively. We investigate two possible causes for the lack of CO emission in these galaxies. On the one hand, there may be a genuine lack of molecular gas in these systems, in spite of the presence of large amounts of neutral gas. However, in the case of IC5152 which is actively forming stars, molecular gas is at least expected to be present in the star forming regions. On the other hand, there may be a large increase in the CO-to-H_2 conversion factor in very low-metallicity dwarfs (-2 <= [Fe/H] <= -1), making CO a poor tracer of the molecular gas content in dwarf galaxies.

A study of the predictive validity of the Kenya certificate of primary education examination : application of hierarchical linear models
Creators: name: Othuon, Lucas A.
Publisher: name: University of British Columbia
Year: 2008

description: Public examinations have been used in Kenya for decades as selection instruments for further education and training. The Kenya Certificate of Primary Education examination (KCPE) is the first of such selection examinations. A basic assumption is that those who pass the examination and are selected to join secondary school have a good chance of succeeding in secondary school. However, evidence that may verify such an assumption, that is, a study of the predictive validity of KCPE, has received little attention. The purpose of this study was to determine the extent to which KCPE predicts success in secondary school. Success in secondary school was measured by the level of examinee achievement in the Kenya Certificate of Secondary Education examination (KCSE). Stratified random sampling was used to select 26 secondary schools within a single district in Kenya. The 1991 KCSE data for 781 examinees in the sample were used in the analysis. The KCSE records for examinees in the sample were matched with corresponding 1987 KCPE records. The nature of the relationship between KCPE and KCSE was determined by use of Hierarchical Linear Models (HLM). The influence of selected moderator variables on the relationship between KCPE and KCSE was investigated as well. These variables were age, gender, repetition of Standard 8 (i.e., writing KCPE more than once), and school size. A moderate linear relationship between KCPE and KCSE was found. The predictive validity did not significantly vary from one school to the other. Of the three pupil-level moderator variables used in this study, only age showed a significant influence on the KCPE-KCSE predictive relationship. A moderate linear relationship, parallel regression slopes, and the extent to which the selected moderator variables influenced the KCPE-KCSE relationship indicate that KCPE is a moderately valid predictor of success in secondary school.

Ειδικότερα επικεντρωθήκαμε στην πρόσληψη του ρυθμού, της μεταφοράς, της ποιητικής εικονοποιίας μέσα από την ενασχόληση των παιδιών με δραστηριότητες που συνόδευαν την ανάγνωση επιλεγμένων ποιητικών κειμένων που περιλαμβάνονταν στο διδακτικό σενάριο «Ποίηση και Τραγούδι». Η όλη διδακτική παρέμβαση σχεδιάστηκε ακολουθώντας τα Νέα Προγράμματα Σπουδών για τη Διδασκαλία της Λογοτεχνίας στην Υποχρεωτική Εκπαίδευση. Επιπλέον, προωθώντας την αισθητική ανάγνωση των ποιημάτων θελήσαμε να διερευνήσουμε τον τρόπο που οι αναγνωστικές και ερμηνευτικές προσεγγίσεις των μικρών αναγνωστών συμβάλλουν προς την κατεύθυνση του πολιτισμικού γραμματισμού, καθώς και τον τρόπο που οι ίδιοι/ες αξιολογούν τη λογοτεχνική εμπειρία που βίωσαν κατά τη διάρκεια του εκπαιδευτικού προγράμματος. Επίσης, οι αναγνωστικές πρακτικές που υιοθετήσαμε φιλοδοξούσαν στην ενίσχυση του διαλόγου στα πλαίσια μιας κοινότητας αναγνωστών με κεντρικό σημείο αναφοράς τα προσωπικά βιώματα των μαθητών/τριών που έρχονταν στην επιφάνεια σε μία πορεία συνάντησης και μείξης με τα ποιητικά κείμενα.
description: The aim of the thesis was to study the response of students of the sixth grade of primary school to basic elements of poetic language. In particular we focused on comprehensing rhythm, metaphor, poetic imagery through the engagement of children in activities that accompanied the reading of selected poetic texts contained in the teaching scenario "Poetry and Song ".The whole teaching intervention was designed following the New Curricula for teaching Literature in Compulsory Education. Furthermore, promoting the aesthetic reading of the poems we wanted to investigate the way the reading and interpretative approaches of young readers contribute towards cultural literacy and how they themselves evaluate the literary experience they had during the educational program. Also, the reading practices adopted aspired to strengthen dialogue within a community of readers with a central point of reference the personal experiences of students coming to the surface in a process of meeting and mixing with the poetic texts.

description: The common practice of quality monitoring in industry relies on manual inspection well-known to be slow, error-prone and operator-dependent. This issue raises strong demand for automated real-time quality monitoring developed from data-driven approaches thus alleviating from operator dependence and adapting to various process uncertainties. Nonetheless, current approaches do not take into account the streaming nature of sensory information while relying heavily on hand-crafted features making them application-specific. This paper proposes the online quality monitoring methodology developed from recently developed deep learning algorithms for data streams, Neural Networks with Dynamically Evolved Capacity (NADINE), namely NADINE++. It features the integration of 1-D and 2-D convolutional layers to extract natural features of time-series and visual data streams captured from sensors and cameras of the injection molding machines from our own project. Real-time experiments have been conducted where the online quality monitoring task is simulated on the fly under the prequential test-then-train fashion - the prominent data stream evaluation protocol. Comparison with the state-of-the-art techniques clearly exhibits the advantage of NADINE++ with 4.68\% improvement on average for the quality monitoring task in streaming environments. To support the reproducible research initiative, codes, results of NADINE++ along with supplementary materials and injection molding dataset are made available in \url{https://github.com/ContinualAL/NADINE-IJCNN2021}.

description: We determine the next-to-leading logarithmic (NLL) QCD corrections to the cross section sigma(e+e- to t bar t H) for center-of-mass energies up to 500 GeV. The dynamics is dominated by nonrelativistic effects, and the summation of terms singular in the relative t bar t velocity is mandatory to all orders in the strong coupling constant alpha_s using an effective theory. The summations lead to an enhancement of the tree level predictions by about a factor of two and are important for the determination of the top Yukawa coupling. We also study the impact of polarization of the electron-positron beams and provide a fast approximation formula for the known O(alpha_s) QCD fixed-order prediction.

description: This article introduces RNA-XC, a theoretical model of a symbolic neural network grounded in the ontological and philosophical foundations of the XChronos project. Departing from conventional neural architectures that rely solely on quantitative data, RNA-XC is designed to recognize and process subjective temporal experiences — such as emotional presence, gaze intensity, silence, and symbolic resonance. Drawing upon concepts like Chronons (units of lived time), Hexachronons (narrative-symbolic blocks), and Metachronos (reflective temporal awareness), this model proposes an alternative path for artificial intelligence: one that responds to meaning, not only behavior; to conscious presence, not just inputs.

The paper reinterprets the symbolic activation threshold through an updated ELAS equation and outlines potential applications in education, therapy, immersive UX design, and ontological metaverses. It invites technologists, philosophers, and creatives to rethink the architecture of intelligent systems as mirrors of lived time, bridging symbolic cognition, poetic computation, and ontological design.

description: We study the prospects of detecting the signal in the stau neutralino co-annihilation region at the LHC using tau leptons. The co-annihilation signal is characterized by the stau and neutralino mass difference (dM) to be 5-15 GeV to be consistent with the WMAP measurement of the cold dark matter relic density as well as all other experimental bounds within the minimal supergravity model. Focusing on tau's from neutralino_2 --> tau stau --> tau tau neutralino_1 decays in gluino and squark production, we consider inclusive MET+jet+3tau production, with two tau's above a high E_T threshold and a third tau above a lower threshold. Two observables, the number of opposite-signed tau pairs minus the number of like-signed tau pairs and the peak position of the di-tau invariant mass distribution, allow for the simultaneous determination of dM and M_gluino. For dM = 9 GeV and M_gluino = 850 GeV with 30 fb^-1 of data, we can measure dM to 15% and M_gluino to 6%.

description: In Touching Feeling: Affect, Pedagogy, and Performance (2003), seminal literary critic and queer theorist Eve Kosofsky Sedgwick coins the term ‘paranoid reading’ to describe the tendency of critics to see their objects of study as having some inherent awe that the critic must unmask. This paranoid reading, contended Sedgwick, deeply prevents critics’ capacity to sense and explore the other sides of an object of study, and most importantly to be open to being surprised by one. In turn, Sedgwick advocates for reparative reading as a mode of reading wherein the critic pushes aside their paranoia and stays open to the internal contradictions and surprises of an object of study. While Kathrin Maurer does not explicitly cite Sedgwick as part of her methodology in The Sensorium of the Drone and Communities (MIT Press, 2023), Maurer certainly captures the spirit of it by providing a rich, compelling reparative reading of drone technology and the communities they enable.

description: In circumstellar disks, the size of dust particles varies from submicron to several centimeters, while planetesimals have sizes of hundreds of kilometers. Therefore, various regimes for the aerodynamic drag between solid bodies and gas can be realized in these disks, depending on the grain sizes and velocities: Epstein, Stokes, and Newton, as well as transitional regimes between them. For small bodies moving in the Epstein regime, the time required to establish the constant relative velocity between the gas and bodies can be much less than the dynamical time scale for the problem - the time for the rotation of the disk about the central body. In addition, the dust may be concentrated in individual regions of the disk, making it necessary to take into account the transfer of momentum between the dust and gas. It is shown that, for a system of equations for gas and monodisperse dust, a semi-implicit first-order approximation scheme in time in which the interphase interaction is calculated implicitly, while other forces, such as the pressure gradient and gravity are calculated explicitly, is suitable for stiff problems with intense interphase interactions and for computations of the drag in non-linear regimes. The piece-wise drag coefficient widely used in astrophysical simulations has a discontinuity at some values of the Mach and Knudsen numbers that are realized in a circumstellar disk. A continuous drag coefficient is presented, which corresponds to experimental dependences obtained for various drag regimes.

description: We investigate slow-light via stimulated Brillouin scattering in a room temperature optical fiber that is pumped by a spectrally broadened laser. Broadening the spectrum of the pump field increases the linewidth $Δω_p$ of the Stokes amplifying resonance, thereby increasing the slow-light bandwidth. One physical bandwidth limitation occurs when the linewidth becomes several times larger than the Brillouin frequency shift $Ω_B$ so that the anti-Stokes absorbing resonance cancels out substantially the Stokes amplifying resonance and hence the slow-light effect. We find that partial overlap of the Stokes and anti-Stokes resonances can actually lead to an enhancement of the slow-light delay - bandwidth product when $Δω_p \simeq 1.3 Ω_B$. Using this general approach, we increase the Brillouin slow-light bandwidth to over 12 GHz from its nominal linewidth of $\sim$30 MHz obtained for monochromatic pumping. We controllably delay 75-ps-long pulses by up to 47 ps and study the data pattern dependence of the broadband SBS slow-light system.

The Banality of Evil (?): The Strange(ly Quiet) Careers of Korematsu and Hirabayashi in the Federal Circuit Courts, 1943‐2016
Creators: name: Dewey, Scott Hamilton
Publisher: name: University of Bologna Law Review
Year: 2022

description: Korematsu v. United States (1944) and Hirabayashi v. United States (1943), the most famous Supreme Court cases associated with the tragic internment of Japanese Americans during World War II, now “live in infamy”, along with the likes of Plessy v. Ferguson and Scott v. Sandford, among the worst constitutional law train-wrecks of American legal history. Ironically, American courts and judges also used the two towering internment cases for their resounding language supporting racial equality and non-discrimination. In either guise, the cases came to cast a long shadow over America’s legal landscape. Thus, it may be somewhat surprising to discover that these two cases long led rather mundane and limited precedential lives in the federal circuit courts, serving repeatedly as precedents in ordinary cases concerning everyday applications of criminal procedure doctrines and displaying little of the brightly hopeful or darkly ominous power for which they would later be known. Whatever greater potential the two cases held, a careful tracking of all uses of the cases in court opinions shows that federal circuit courts mostly did not explore that potential until after it was “safe” to do so. In particular, although the Japanese Internment was fundamentally a legal and constitutional problem, federal courts proved to be largely unable to confront that problem meaningfully until after some sort of political “solution” was offered by Congress through formal apology and reparations to internment survivors in 1988. Only later did federal circuit judges use the two cases more aggressively, with Korematsu suddenly serving as a dire warning of the dangers of judicial reticence in resisting constitutional overreaching by the legislative or executive branches, while Hirabayashi was brandished to support strict, color-blind racial equality—long after civil rights progress was already waning.

We verify by Montecarlo numerical simulations the crossover from local mean field behavior to global paramagnetism. We investigate the behavior of correlations and find that in the low temperature phase correlations grow at a faster rate then the interaction range. We completely characterize the growth of correlations in the vicinity of the mean-field critical region.

description: We report on the submillimeter properties of Sagittarius A* derived from observations with the Submillimeter Array and its polarimeter. We find that the spectrum of Sgr A* between 230 and 690 GHz is slightly decreasing when measured simultaneously, indicating a transition to optically thin emission around 300-400 GHz. We also present very sensitive and well calibrated measurements of the polarization of Sgr A* at 230 and 345 GHz. With these data we are able to show for the first time that the polarization of Sgr A* varies on hour timescales, as has been observed for the total intensity. On one night we find variability that may arise from a polarized "blob" orbiting the black hole. Finally, we use the ensemble of observations to determine the rotation measure. This represents the first statistically significant rotation measure determination and the only one made without resorting to comparing position angles measured at separate epochs. We find a rotation measure of (-5.6+/-0.7)x10^5 rad/m^2, with no evidence for variability on inter-day timescales at the level of the measurement error. The stability constrains interday fluctuations in the accretion rate to 8%. The mean intrinsic polarization position angle is 167+/-7 degrees and we detect variations of 31+18/-9 degrees. This separation of intrinsic polarization changes and possible rotation measure fluctuations is now possible because of the frequency coverage and sensitivity of our data. The observable rotation measure restricts the accretion rate to the range 2x10^{-7} Msun/yr to 2x10^{-9} Msun/yr, if the magnetic field is near equipartition and ordered.

Για κάθε γεωυλικό παρουσιάζεται ένα εύρος τιμών (μέγιστες – ελάχιστες τιμές). Τέλος, διερευνάται ποιο σύστημα είναι πιο αντιπροσωπευτικό και εκτιμάται η συμπεριφορά των βραχομαζών που συναντήθηκαν.
description: In this study, the geotechnical classification of flysch rock masses using the GSI and RMR systems is examined, focused on the area of the underground works of Metsovitikos Hydroelectric Project. It consists of lots of underground works (6km of tunnels) and two large (and rare) excavations, one for the power plant (35m high, 35m long and 17m wide) and a second for the power tunnel surge tank (114m high, vertical shaft). This formation is characterized as difficult for tunneling. The flysch bedrock in Metsovitikos area integrates into the Ionian geological zone. The area has also undergone highly tectonic disturbance due to Pindos thrust above Ionian flysch. In this study, first, the specific characteristics of the project are presented. Then, the geological and geotechnical data referring to the geomaterials (mainly sandstones and conglomerates) that consist the bedrock at the area of study is analyzed. The evaluation is based on all existing data from the drilled boreholes (24 holes) and in situ observations. The final part of this study includes the geotechnical classification of each rock type of flysch based on GSI and RMR systems. The evaluation of their expected geotechnical behaviour in underground excavations and the required primary support measures are identified.

description: We report a systematic determination of the responses of PandaX-II, a dual phase xenon time projection chamber detector, to low energy recoils. The electron recoil (ER) and nuclear recoil (NR) responses are calibrated, respectively, with injected tritiated methane or $^{220}$Rn source, and with $^{241}$Am-Be neutron source, within an energy range from $1-25$ keV (ER) and $4-80$ keV (NR), under the two drift fields of 400 and 317 V/cm. An empirical model is used to fit the light yield and charge yield for both types of recoils. The best fit models can well describe the calibration data. The systematic uncertainties of the fitted models are obtained via statistical comparison against the data.

On Anisotropic Dark Energy

description: Since the discovery of the accelerated expansion of the universe, it was necessary to introduce a new component of matter distribution called dark energy. The standard cosmological model considers isotropy of the pressure and assumes an equation of state $p=ωρ$, relating the pressure $p$ and the energy density $ρ$. The interval of the parameter $ω$ defines the kind of matter of the universe, related to the fulfillment, or not, of the energy conditions of the fluid. The recent interest in this kind of fluid with anisotropic pressure, in the scenario of the gravitational collapse and star formation, imposes a carefull analysis of the energy conditions and the role of the components of the pressure. Here, in this work, we show an example where the classification of dark energy for isotropic pressure fluids is used incorrectly for anisotropic fluids. The correct classification and its consequences are presented.

A new spectral apparent horizon finder for 3D numerical relativity

description: We present a new spectral-method-based algorithm for finding apparent horizons in three-dimensional space-like hypersurfaces without symmetries. While there are already a wide variety of algorithms for finding apparent horizons, our new algorithm does not suffer from the same weakness as previous spectral apparent horizon finders: namely the monopolar coefficient ($\ell=0$ in terms of the spherical harmonics decomposition) needed to be determined by a root-finding procedure. Hence, this leads to a much faster and more robust spectral apparent horizon finder. The finder is tested with the Kerr-Schild and Brill-Lindquist data. Our finder is accurate and is as efficient as the currently fastest methods developed recently by Schnetter (2003 Class. Quantum Grav. {\bf 20}, 4719) and Thornburg (2004 Class. Quantum Grav. {\bf 21}, 743). At typical resolutions it takes only 0.5 second to find the apparent horizon of a Kerr-Schild black hole with $a=0.9M$ to the accuracy $\sim 10^{-5}$ for the fractional error in the horizon's location on a 2 GHz processor.

description: We discover multipole-mode solitons supported by the surface between two distinct periodic lattices imprinted in Kerr-type nonlinear media. Such solitons are possible because the refractive index modulation at both sides of the interface glues together their out-of-phase individual constituents. Remarkably, we find that the new type of solitons may feature highly asymmetric shapes and yet they are stable over wide domains of their existence, a rare property to be attributed to their surface nature.

description: The honeycomb lattice in the cylinder geometry with zigzag edges, bearded edges, zigzag and bearded edges (zigzag-bearded), and armchair edges are studied. The tight-binding model with nearest-neighbor hoppings is used. Edge states are obtained analytically for these edges except the armchair edges. It is shown, however, that edge states for the armchair edges exist when the the system is anisotropic. These states have not been known previously. We also find strictly localized states, uniformly extended states and states with macroscopic degeneracy.

A variational approach to the stochastic aspects of cellular signal transduction

description: Cellular signaling networks have evolved to cope with intrinsic fluctuations, coming from the small numbers of constituents, and the environmental noise. Stochastic chemical kinetics equations govern the way biochemical networks process noisy signals. The essential difficulty associated with the master equation approach to solving the stochastic chemical kinetics problem is the enormous number of ordinary differential equations involved. In this work, we show how to achieve tremendous reduction in the dimensionality of specific reaction cascade dynamics by solving variationally an equivalent quantum field theoretic formulation of stochastic chemical kinetics. The present formulation avoids cumbersome commutator computations in the derivation of evolution equations, making more transparent the physical significance of the variational method. We propose novel time-dependent basis functions which work well over a wide range of rate parameters. We apply the new basis functions to describe stochastic signaling in several enzymatic cascades and compare the results so obtained with those from alternative solution techniques. The variational ansatz gives probability distributions that agree well with the exact ones, even when fluctuations are large and discreteness and nonlinearity are important. A numerical implementation of our technique is many orders of magnitude more efficient computationally compared with the traditional Monte Carlo simulation algorithms or the Langevin simulations.

description: In this study, using low-temperature scanning tunneling microscopy (STM), we focus on understanding the native defects in pristine \textit{1T}-TiSe$_2$ at the atomic scale. We probe how they perturb the charge density waves (CDWs) and lead to local domain formation. These defects influence the correlation length of CDWs. We establish a connection between suppression of CDWs, Ti intercalation, and show how this supports the exciton condensation model of CDW formation in \textit{1T}-TiSe$_2$.

description: The purpose of this article is to set foundations for decomposition numbers of perverse sheaves, to give some methods to calculate them in simple cases, and to compute them concretely in two situations: for a simple (Kleinian) surface singularity, and for the closure of the minimal non-trivial orbit in a simple Lie algebra. This work has applications to modular representation theory, for Weyl groups using the nilpotent cone of the corresponding semisimple Lie algebra, and for reductive algebraic group schemes using the affine Grassmannian of the Langlands dual group.

description: We present a method to compute the magnification of a finite source star lensed by a triple lens system based on the image boundary (contour integration) method. We describe a new procedure to obtain continuous image boundaries from solutions of the tenth-order polynomial obtained from the lens equation. Contour integration is then applied to calculate the image areas within the image boundaries, which yields the magnification of a source with uniform brightness. We extend the magnification calculation to limb-darkened stars approximated with a linear profile. In principle, this method works for all multiple lens systems, not just triple lenses. We also include an adaptive sampling and interpolation method for calculating densely covered light curves. The C++ source code and a corresponding Python interface are publicly available.
