description: We study the ground state and the magnetization process of a spin-1/2 $J_1$-$J_2$ model with a plaquette structure by using various methods. For small inter-plaquette interaction, this model is expected to have a spin-gap and we computed the first- and the second excitation energies. If the gap of the lowest excitation closes, the corresponding particle condenses to form magnetic orders. By analyzing the quintet gap and magnetic interactions among the quintet excitations, we find a spin-nematic phase around $J_1/J_2\sim -2$ due to the strong frustration and the quantum effect. When high magnetic moment is applied, not the spin-1 excitations but the spin-2 ones soften and dictate the magnetization process. We apply a mean-field approximation to the effective Hamiltonian to find three different types of phases (a conventional BEC phase, ``striped'' supersolid phases and a 1/2-plateau). Unlike the BEC in spin-dimer systems, this BEC phase is not accompanied by transverse magnetization. Possible connection to the recently discovered spin-gap compound (CuCl)LaNb2O7 is discussed.

description: Long-standing unexplained Venus atmosphere observations and chemical anomalies point to unknown chemistry but also leave room for the possibility of life. The unexplained observations include several gases out of thermodynamic equilibrium (e.g. tens of ppm O2, the possible presence of PH3 and NH3, SO2 and H2O vertical abundance profiles), an unknown composition of large, lower cloud particles, and the "unknown absorber(s)". Here we first review relevant properties of the Venus atmosphere and then describe the atmospheric chemical anomalies and how they motivate future astrobiology missions to Venus.

description: Nelle interazioni quotidiane si utilizzano molto spesso metafore, espressioni idiomatiche e unità lessicali che possiedono un forte grado di idiomaticità. Il linguaggio figurato non appartiene, infatti, solo alla retorica di poeti e scrittori, ma rappresenta una risorsa imprescindibile per ogni parlante nei contesti comunicativi di ogni giorno. Frasi idiomatiche, collocazioni, co-occorrenze, forme routinizzate e cristallizzate costituiscono una componente rilevante del corpus lessicale di una lingua. Tuttavia, per la loro stessa natura, esse presentano alcune difficoltà nel loro apprendimento. Tali espressioni, infatti, sono trasparenti all'interno di una determinata comunità linguistica, ma possono essere incomprensibili o di difficile interpretazione per coloro che apprendono una lingua straniera, perché in molti casi in esse il significato normale delle parole viene disatteso. Inoltre, nella prassi didattica e nei testi, la riflessione sul linguaggio figurato viene generalmente trascurata e l'apprendimento delle espressioni idiomatiche è spesso relegato ad attività poco significative e marginali. Nel presente contributo sono descritte le caratteristiche principali delle forme idiomatiche sotto il profilo psicolinguistico e vengono proposte alcune indicazioni metodologiche, nella speranza che nei corsi di lingua si risvegli una nuova attenzione verso il lessico ed in particolare verso gli aspetti del linguaggio figurato e degli idioms.

description: Current optical vegetation indices (VIs) for monitoring forest ecosystems are well established and widely used in various applications, but can be limited by atmospheric effects such as clouds. In contrast, synthetic aperture radar (SAR) data can offer insightful and systematic forest monitoring with complete time series (TS) due to signal penetration through clouds and day and night image acquisitions. This study aims to address the limitations of optical satellite data by using SAR data as an alternative for estimating optical VIs for forests through machine learning (ML). While this approach is less direct and likely only feasible through the power of ML, it raises the scientific question of whether enough relevant information is contained in the SAR signal to accurately estimate VIs. This work covers the estimation of TS of four VIs (LAI, FAPAR, EVI and NDVI) using multitemporal Sentinel-1 SAR and ancillary data. The study focused on both healthy and disturbed temperate forest areas in Czechia for the year 2021, while ground truth labels generated from Sentinel-2 multispectral data. This was enabled by creating a paired multi-modal TS dataset in Google Earth Engine (GEE), including temporally and spatially aligned Sentinel-1, Sentinel-2, DEM, weather and land cover datasets. The inclusion of DEM-derived auxiliary features and additional meteorological information, further improved the results. In the comparison of ML models, the traditional ML algorithms, RFR and XGBoost slightly outperformed the AutoML approach, auto-sklearn, for all VIs, achieving high accuracies ($R^2$ between 70-86%) and low errors (0.055-0.29 of MAE). In general, up to 240 measurements per year and a spatial resolution of 20 m can be achieved using estimated SAR-based VIs with high accuracy. A great advantage of the SAR-based VI is the ability to detect abrupt forest changes with sub-weekly temporal accuracy.

Analysis of Time Scale to Consensus in Voting Dynamics with more than Two Options

description: We generalize a binary majority-vote model on adaptive networks to its plurality-vote counterpart and analyze the time scale to consensus when voters are given more than two options. When opinions are uniformly distributed in the population of voters in the initial state, we find that the time scale to consensus is shorter than the binary vote model from both numerical simulations and mathematical analysis using the master equation for the three-state plurality-vote model. When intervention such as opinion conversion is allowed, as in the case of sudden change of mind of voter for any reason, the effort needed to push the fragmented three-opinion population in the thermodynamic limit to the consensus state, measured in minimal intervention cost, is less than that needed to push a polarized two-opinion population to the consensus state, when the degree ($p$) of homophily is less than 0.8. For finite system, the fragmented three-opinion population will spontaneously reach the consensus state, with faster time to consensus, compared to polarized two-opinion population, for a broad range of $p$.

"LANGUAGE ACQUISITIONAL STORYTELLING": PSYCHOLINGUISTICS IN ACTION IN THE ITALIAN EFL CLASSROOM

Subjects: story telling; psicolinguistica; inglese Lingua straniera

description: The aim of the present paper is to analyse the educational activity of storytelling from an innovative perspective: storytelling as a "psycholinguistic" teaching/learning tool, which can effectively facilitate the acquisition of English as a foreign language by presenting a story through the main stages of acquisition of English as a first language. The educational context where this new teaching/learning strategy is proposed is the class of English language/culture in Italian primary schools. In particular, a new typology of storytelling will be here presented and examined, under the definition of "language acquistional storytelling". This teaching/learning tool can enable teachers to expose their pupils to simple stories in English, in which the language is gradually construed through the main stages of acquisition of English as a first language, and is at the same time adapted to the specific context of teaching/learning English as a foreign language. In the course of our discussion, some examples derived from an English children's book "There's an Alligator under My Bed" by Mercer Meyer will be offered. Alongside, this teaching/learning proposal intends to suggest some creative activities and games which can help pupils understand, employ, internalize and reemploy the language forms and rules that are inductively introduced by the teacher in the course of the narration itself.

Bayes Conditional Distribution Estimation for Knowledge Distillation Based on Conditional Mutual Information

description: It is believed that in knowledge distillation (KD), the role of the teacher is to provide an estimate for the unknown Bayes conditional probability distribution (BCPD) to be used in the student training process. Conventionally, this estimate is obtained by training the teacher using maximum log-likelihood (MLL) method. To improve this estimate for KD, in this paper we introduce the concept of conditional mutual information (CMI) into the estimation of BCPD and propose a novel estimator called the maximum CMI (MCMI) method. Specifically, in MCMI estimation, both the log-likelihood and CMI of the teacher are simultaneously maximized when the teacher is trained. Through Eigen-CAM, it is further shown that maximizing the teacher's CMI value allows the teacher to capture more contextual information in an image cluster. Via conducting a thorough set of experiments, we show that by employing a teacher trained via MCMI estimation rather than one trained via MLL estimation in various state-of-the-art KD frameworks, the student's classification accuracy consistently increases, with the gain of up to 3.32\%. This suggests that the teacher's BCPD estimate provided by MCMI method is more accurate than that provided by MLL method. In addition, we show that such improvements in the student's accuracy are more drastic in zero-shot and few-shot settings. Notably, the student's accuracy increases with the gain of up to 5.72\% when 5\% of the training samples are available to the student (few-shot), and increases from 0\% to as high as 84\% for an omitted class (zero-shot).

The orientation of Eta Carinae and the powering mechanism of intermediate luminosity optical transients (ILOTs)

Publisher: name: arXiv
Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Contrary to recent claims, we argue that the orientation of the massive binary system Eta Carinae is such that the secondary star is closer to us at periastron passage, and it is on the far side during most of the time of the eccentric orbit. The binary orientation we dispute is based on problematic interpretations of recent observations. Among these observations are the radial velocity of the absorption component of He I P-Cyg lines, of the He II $\lambda4686$ emission line, and of the Br$γ$ line emitted by clumps close to the binary system. We also base our orientation on observations of asymmetric molecular clumps that were recently observed by ALMA around the binary system, and were claimed to compose a torus with a missing segment. The orientation has implications for the modeling of the binary interaction during the nineteenth century Great Eruption (GE) of Eta Carinae that occurred close to periastron passage. The orientation where the secondary is closer to us at periastron leads us to suggest that the mass-missing side of the molecular clumps is a result of accretion onto the secondary star during the periastron passage when the clumps were ejected, probably during the GE. The secondary star accreted a few solar masses during the GE and the energy from the accretion process consists the majority of the GE energy. This in turn strengthens the more general model according to which many intermediate-luminosity optical transients (ILOTs) are powered by accretion onto a secondary star.

description: We characterise the intra-cluster light (ICL) in ensembles of full-physics cluster simulations from The Three Hundred project, a suite of 324 hydrodynamical resimulations of cluster-sized halos. We identify the ICL as those stellar particles bound to the potential of the cluster itself, but not to any of its substructures, and separate the brightest cluster galaxy (BCG) by means of a fixed 50 kpc aperture. We find the total BCG+ICL mass to be in agreement with state-of-the-art observations of galaxy clusters. The ICL mass fraction of our clusters is between 30 and 50 per cent of the total stellar mass within $R_{500}$, while the BCG represents around 10 percent. We further find no trend of the ICL fraction with cluster halo mass, at least not in the range $[0.2,3]\cdot10^{15}h^{-1}M_\odot$ considered here. For the dynamical state, characterised both by theoretical estimators and by the recent merging history of the cluster, there is a clear correlation, such that more relaxed clusters and those that have undergone fewer recent mergers have a higher ICL fraction. Finally, we investigate the possibility of using the ICL to explore the dark matter (DM) component of galaxy clusters. We compute the volumetric density profile for the DM and ICL components and show that, up to $R_{500}$, the ratio between the two can be described by a power law. Working with the velocity dispersion profiles instead, we show that the ratio can be fit by a straight line. Providing the parameters of these fits, we show how the ICL can be used to infer DM properties.

description: We develop quantum information processing primitives for the planar rotor, the state space of a particle on a circle. By interpreting rotor wavefunctions as periodically identified wavefunctions of a harmonic oscillator, we determine the group of bosonic Gaussian operations inherited by the rotor. This $n$-rotor Clifford group, $\text{U}(1)^{n(n+1)/2} \rtimes \text{GL}_n(\mathbb{Z})$, is represented by continuous $\text{U}(1)$ gates generated by polynomials quadratic in angular momenta, as well as discrete $\text{GL}_n(\mathbb Z)$ momentum sign-flip and sum gates. We classify homological rotor error-correcting codes [arXiv:2303.13723] and various rotor states based on equivalence under Clifford operations.
 Reversing direction, we map homological rotor codes and rotor Clifford operations back into oscillators by interpreting occupation-number states as rotor states of non-negative angular momentum. This yields new multimode homological bosonic codes protecting against dephasing and changes in occupation number, along with their corresponding encoding and decoding circuits. In particular, we show how to non-destructively measure the oscillator phase using conditional occupation-number addition and post selection. We also outline several rotor and oscillator varieties of the GKP-stabilizer codes [arXiv:1903.12615].

description: We calculate the force of a near-resonant guided light field of an ultrathin optical fiber on a two-level atom. We show that, if the atomic dipole rotates in the meridional plane, the magnitude of the force of the guided light depends on the field propagation direction. The chirality of the force arises as a consequence of the directional dependencies of the Rabi frequency of the guided driving field and the spontaneous emission from the atom. This provides a unique method for controlling atomic motion in the vicinity of an ultrathin fiber.

Esso facilita il passaggio dalla ricettività alla produttività; crea le condizioni affinché l'input linguistico si trasferisca dal sistema della memoria temporanea a quella a lungo termine; agevola l'attivazione di meccanismi simili all'apprendimento naturale della lingua straniera; valorizza non solo l'intelligenza linguistica ma anche quelle necessarie allo studio dei contenuti che si vogliono veicolare in LS; aumenta la motivazione allo studio perché la LS è utilizzata in situazioni di studio reale, diverse dalle simulazioni tipiche dell'insegnamento tradizionale della lingua straniera. Questo approccio, che spesso è definito innovativo ma che la storia ci insegna essere abbastanza antico, si sta facendo strada tra i metodi di insegnamento tradizionali, anche se non è semplice organizzare percorsi CLIL curriculari in una scuola che non prevede compresenze.

description: Detection schemes for the quantum chromodynamics axions and other axion-like particles in light-shining-through-a-wall (LSW) experiments are based on the conversion of these particles into photons in a magnetic field. An alternative scheme may involve the detection via a resonant atomic or molecular transition induced by resonant axion absorption. The signal obtained in this process is second order in the axion-electron interaction constant but may become first order if we allow interference between the axion-induced transition amplitude and the transition amplitude induced by the electromagnetic radiation that produces the axions.

description: Il collegamento tra cultura e lingua, soprattutto nell’insegnamento di una L2, assume un ruolo particolare nella classe di lingue e con apprendenti adulti, che si trovano infatti ad imparare una lingua immersi nella realtà socio-culturale del relativo paese. Nel caso di studenti in mobilità Erasmus si aggiungono anche elementi di vissuto socio-affettivo che potrebbero trovare una collocazione all’interno della classe di lingua, al fine di capitalizzare un’esperienza breve ma intensa di contatto con aspetti di una cultura altra. L’articolo descrive le fasi del Progetto Dossier, realizzato presso il CLA dell’Università degli Studi di Verona, ove esperienze di vissuto socio-culturale degli apprendenti sono state inglobate nella programmazione didattica e divenute momento di apprendimento e condivisione per tutto il gruppo-classe. In particolare si riportano alcune tra le esperienze degli studenti del livello A2, significative sia in relazione al livello di conoscenza della lingua di questo gruppo che come testimonianze di coniugazione tra interessi personali ed aspetti legati al soggiorno in Italia.

description: Un nuovo fenomeno che è sotto gli occhi di tutti è la presenza sempre più massiccia nei corsi di lingua straniera di studenti "in là con gli anni". Ciò nonostante la ricerca in glottodidattica stenta a riconoscerli come un pubblico a parte, attribuendogli motivazioni, stili e bisogni simili a coloro che hanno 20 o 30 anni di meno. Il presente contributo ha, quindi, tra i suoi obiettivi proprio quello di avviare una riflessione su questo target di apprendenti al fine di sostenere al meglio il loro percorso di apprendimento favorendo, così, quell'apprendimento lungo l'arco di tutta la vita più volte richiamato tra gli obiettivi della formazione linguistica in ambito europeo. Il rapporto tra over 55 e lingue straniere si è modificato in conseguenza dei cambiamenti in atto nella nostra società che, come mostreremo, hanno creato le condizioni per nuovi bisogni linguistici orientati all'utilizzo delle L2. Ma quali sono le L2 maggiormente apprese da questi apprendenti? Perché scelgono di entrare o di rientrare in formazione rivolta alla L2? Quali sono le tecniche didattiche preferite una volta entrati in un corso di lingua? A queste domande si risponderà mostrando i risultati di un'ampia indagine su un campione di apprendenti over 55 attualmente inseriti in percorsi di apprendimento di varie lingue straniere sparsi su tutto il territorio nazionale.

description: Current long-baseline accelerator experiments, NOvA and T2K, are making excellent measurements of neutrino oscillations and the next generation of experiments, DUNE and HK, will make measurements at the $\mathcal O(1\%)$ level of precision. These measurements are a combination of the appearance channel which is more challenging experimentally but depends on many oscillation parameters, and the disappearance channel which is somewhat easier and allows for precision measurements of the atmospheric mass splitting and the atmospheric mixing angle. It is widely recognized that the matter effect plays a key role in the appearance probability, yet the effect on the disappearance probability is surprisingly small for these experiments. Here we investigate both exactly how small the effect is and show that it just begins to become relevant in the high statistics regime of DUNE.

description: We report the synthesis and biological evaluation of a new series of 3- or 4-(substituted)phenylisoxazolones as HNE inhibitors. Due to tautomerism of the isoxazolone nucleus, two isomers were obtained as final compounds (2-NCO and 5-OCO) and the 2-NCO derivatives were the most potent with IC50 values in the nanomolar range (20–70 nM). Kinetic experiments indicated that 2-NCO 7d and 5-OCO 8d are both competitive HNE inhibitors. Molecular modelling on 7d and 8d suggests for the latter a more crowded region about the site of the nucleophilic attack, which could explain its lowered activity. In addition molecular dynamics (MD) simulations showed that the isomer 8d appears more prone to form H-bond interactions which, however, keep the reactive sites quite distant for the attack by Ser195. By contrast the amide 7d appears more mobile within the active pocket, since it makes single H-bond interactions affording a favourable orientation for the nucleophilic attack.

description: Magnetars are slowly rotating neutron stars that possess the strongest magnetic fields ($10^{14}-10^{15} \mathrm{G}$) known in the cosmos. They display a range of transient high-energy electromagnetic activity. The brightest and most energetic of these events are the gamma-ray bursts (GRBs) known as magnetar giant flares (MGFs), with isotropic energy $E\approx10^{44}-10^{46} \mathrm{erg}$. There are only seven detections identified as MGFs to date: three unambiguous events occurred in our Galaxy and the Magellanic Clouds, and the other four MGF candidates are associated with nearby star-forming galaxies. As all seven identified MGFs are bright at Earth, additional weaker events remain unidentified in archival data. We conducted a search of the Fermi Gamma-ray Burst Monitor (GBM) database for candidate extragalactic MGFs and, when possible, collected localization data from the Interplanetary Network (IPN) satellites. Our search yielded one convincing event, GRB 180128A. IPN localizes this burst with NGC 253, commonly known as the Sculptor Galaxy. This event is the second MGF in modern astronomy to be associated with this galaxy and the first time two bursts are associated with a single galaxy outside our own. Here, we detail the archival search criteria that uncovered this event and its spectral and temporal properties, which are consistent with expectations for a MGF. We also discuss the theoretical implications and finer burst structures resolved from various binning methods. Our analysis provides observational evidence for an eighth identified MGF.

description: Dictation enables efficient text input on mobile devices. However, writing with speech can produce disfluent, wordy, and incoherent text and thus requires heavy post-processing. This paper presents Rambler, an LLM-powered graphical user interface that supports gist-level manipulation of dictated text with two main sets of functions: gist extraction and macro revision. Gist extraction generates keywords and summaries as anchors to support the review and interaction with spoken text. LLM-assisted macro revisions allow users to respeak, split, merge and transform dictated text without specifying precise editing locations. Together they pave the way for interactive dictation and revision that help close gaps between spontaneous spoken words and well-structured writing. In a comparative study with 12 participants performing verbal composition tasks, Rambler outperformed the baseline of a speech-to-text editor + ChatGPT, as it better facilitates iterative revisions with enhanced user control over the content while supporting surprisingly diverse user strategies.

description: We have investigated radio-frequency single-electron transistor (RF-SET) operation of single-walled carbon nanotube quantum dots in the strong tunneling regime. At 4.2 K and carrier frequency 754.2 MHz, we reach a charge sensitivity of 2.3e-6 e/Hz^(1/2) over a bandwidth of 85 MHz. Our results indicate a gain-bandwidth product of 3.7e13 Hz^(3/2)/e, which is by one order of magnitude better than for typical RF-SETs.

description: We experimentally investigate spin-orbit torque and spin pumping in Y$_3$Fe$_5$O$_{12}$(YIG)/Pt bilayers with ultrathin insertion layers at the interface. An insertion layer of Cu suppresses both spin-orbit torque and spin pumping, whereas an insertion layer of Ni$_{80}$Fe$_{20}$ (permalloy, Py) enhances them, in a quantitatively consistent manner with the reciprocity of the two spin transmission processes. However, we observe a large enhancement of Gilbert damping with the insertion of Py that cannot be accounted for solely by spin pumping, suggesting significant spin-memory loss due to the interfacial magnetic layer. Our findings indicate that the magnetization at the YIG-metal interface strongly influences the transmission and depolarization of pure spin current.

description: {}From a finite-size scaling (FSS) theory of cumulants of the order parameter at phase coexistence points, we reconstruct the scaling of the moments. Assuming that the cumulants allow a reconstruction of the free energy density no better than as an asymptotic expansion, we find that FSS for moments of low order is still complete. We suggest ways of using this theory for the analysis of numerical simulations. We test these methods numerically through the scaling of cumulants and moments of the magnetization in the low-temperature phase of the two-dimensional Ising model.

description: As systems approaches to the development of biological models become more mature, attention is increasingly focusing on the problem of inferring parameter values within those models from experimental data. However, particularly for nonlinear models, it is not obvious, either from inspection of the model or from the experimental data, that the inverse problem of parameter fitting will have a unique solution, or even a non-unique solution that constrains the parameters to lie within a plausible physiological range. Where parameters cannot be constrained they are termed ‘unidentifiable’. We focus on gaining insight into the causes of unidentifiability using inference-based methods, and compare a recently developed measure-theoretic approach to inverse sensitivity analysis to the popular Markov Chain Monte Carlo and Approximate Bayesian Computation techniques for Bayesian inference. All three approaches map the uncertainty in quantities of interest in the output space to the probability of sets of parameters in the input space. The geometry of these sets demonstrates how unidentifiability can be caused by parameter compensation and provides an intuitive approach to inference-based experimental design.
L’ABILITÀ DI LETTURA E LO SVILUPPO DELLA COMPETENZA LESSICALE

description: Numerose ricerche in ambito psicolinguistico e glottodidattico confermano l’importante relazione tra lo sviluppo della competenza lessicale e l’abilità di lettura. Da un lato, infatti, l’espansione del lessico consente una maggior fluency nella lettura, dall’altro quest’ultima facilita l’acquisizione del lessico attraverso ripetute e graduali esposizioni (extensive reading, cfr. Krashen 1989). A partire dagli anni settanta, in ambito cognitivista, sono state proposte diverse teorie sulla lettura intesa come processo attivo e creativo della mente (processi bottom-up, top-down e integrati). Ciò ha spinto la glottodidattica a ridefinire il ruolo dell’abilità di lettura nell’apprendimento delle lingue superando la concezione del metodo audio-orale in cui reading was simply speach written down, and therefore the process of learning to read was seen basically as a matter of developing habitual and mechanical recognition of the written symbols which correspond to know (speach) patterns (Coady 1993: 6). A partire dagli anni ottanta-novanta, inoltre, il lessico, fino ad allora praticamente ignorato nella didattica delle lingue, è divenuto oggetto di molti studi, alcuni dei quali relativi al rapporto con l’abilità di lettura. Questo contributo si propone da un lato di definire cosa si intenda per competenza lessicale e dall’altro di descrivere alcuni meccanismi del processo di lettura, per infine proporre alcune riflessioni glottodidattiche di carattere metodologico-applicativo.

description: The use of the loudest observed event to generate statistical statements about rate and strength has become standard in searches for gravitational waves from compact binaries and pulsars. The Bayesian formulation of the method is generalized in this paper to allow for uncertainties both in the background estimate and in the properties of the population being constrained. The method is also extended to allow rate interval construction. Finally, it is shown how to combine the results from multiple experiments and a comparison is drawn between the upper limit obtained in a single search and the upper limit obtained by combining the results of two experiments each of half the original duration. To illustrate this, we look at an example case, motivated by the search for gravitational waves from binary inspiral.

description: This article delves into the analysis of performance and utilization of Support Vector Machines (SVMs) for the critical task of forest fire detection using image datasets. With the increasing threat of forest fires to ecosystems and human settlements, the need for rapid and accurate detection systems is of utmost importance. SVMs, renowned for their strong classification capabilities, exhibit proficiency in recognizing patterns associated with fire within images. By training on labeled data, SVMs acquire the ability to identify distinctive attributes associated with fire, such as flames, smoke, or alterations in the visual characteristics of the forest area. The document thoroughly examines the use of SVMs, covering crucial elements like data preprocessing, feature extraction, and model training. It rigorously evaluates parameters such as accuracy, efficiency, and practical applicability. The knowledge gained from this study aids in the development of efficient forest fire detection systems, enabling prompt responses and improving disaster management. Moreover, the correlation between SVM accuracy and the difficulties presented by high-dimensional datasets is carefully investigated, demonstrated through a revealing case study. The relationship between accuracy scores and the different resolutions used for resizing the training datasets has also been discussed in this article. These comprehensive studies result in a definitive overview of the difficulties faced and the potential sectors requiring further improvement and focus.

description: Most molecular diagram parsers recover chemical structure from raster images (e.g., PNGs). However, many PDFs include commands giving explicit locations and shapes for characters, lines, and polygons. We present a new parser that uses these born-digital PDF primitives as input. The parsing model is fast and accurate, and does not require GPUs, Optical Character Recognition (OCR), or vectorization. We use the parser to annotate raster images and then train a new multi-task neural network for recognizing molecules in raster images. We evaluate our parsers using SMILES and standard benchmarks, along with a novel evaluation protocol comparing molecular graphs directly that supports automatic error compilation and reveals errors missed by SMILES-based evaluation. On the synthetic USPTO benchmark, our born-digital parser obtains a recognition rate of 98.4% (1% higher than previous models) and our relatively simple neural parser for raster images obtains a rate of 85% using less training data than existing neural approaches (thousands vs. millions of molecules).
