We prove several conjectures relating the existence of nonvanishing 1- forms to smooth morphisms over abelian varieties, assuming the existence of good minimal models. The proof involves a decomposition result for a family of Calabi-Yau varieties equipped with a surjective map to an abelian scheme. In the uniruled case, supposing the MRC base admits a good minimal model, we also achieve a structure theorem for those varieties admitting nowhere vanishing 1-forms.
Scientific literature understanding is crucial for extracting targeted information and garnering insights, thereby significantly advancing scientific discovery. Despite the remarkable success of Large Language Models (LLMs), they face challenges in scientific literature understanding, primarily due to (1) a lack of scientific knowledge and (2) unfamiliarity with specialized scientific tasks. To develop an LLM specialized in scientific literature understanding, we propose a hybrid strategy that integrates continual pre-training (CPT) and supervised fine-tuning (SFT), to simultaneously infuse scientific domain knowledge and enhance instruction-following capabilities for domain-specific tasks.cIn this process, we identify two key challenges: (1) constructing high-quality CPT corpora, and (2) generating diverse SFT instructions. We address these challenges through a meticulous pipeline, including PDF text extraction, parsing content error correction, quality filtering, and synthetic instruction creation. Applying this strategy, we present a suite of LLMs: SciLitLLM, specialized in scientific literature understanding. These models demonstrate promising performance on scientific literature understanding benchmarks. Our contributions are threefold: (1) We present an effective framework that integrates CPT and SFT to adapt LLMs to scientific literature understanding, which can also be easily adapted to other domains. (2) We propose an LLM-based synthesis method to generate diverse and high-quality scientific instructions, resulting in a new instruction set -- SciLitIns -- for supervised fine-tuning in less-represented scientific domains. (3) SciLitLLM achieves promising performance improvements on scientific literature understanding benchmarks.

Neuromorphic visual sensors are artificial retinas that output sequences of asynchronous events when brightness changes occur in the scene. These sensors offer many advantages including very high temporal resolution, no motion blur and smart data compression ideal for real-time processing. In this study, we introduce an event-based dataset on fine-grained manipulation actions and perform an experimental study on the use of transformers for action prediction with events. There is enormous interest in the fields of cognitive robotics and human-robot interaction on understanding and predicting human actions as early as possible. Early prediction allows anticipating complex stages for planning, enabling effective and real-time interaction. Our Transformer network uses events to predict manipulation actions as they occur, using online inference. The model succeeds at predicting actions early on, building up confidence over time and achieving state-of-the-art classification. Moreover, the attention-based transformer architecture allows us to study the role of the spatio-temporal patterns selected by the model. Our experiments show that the Transformer network captures action dynamic features outperforming video-based approaches and succeeding with scenarios where the differences between actions lie in very subtle cues. Finally, we release the new event dataset, which is the first in the literature for manipulation action recognition. Code will be available at https://github.com/DaniDeniz/EventVisionTransformer.

We report resonant elastic X-ray scattering (REXS) of long-range magnetic order in EuPtSi$_{\text{3}}$, combining different scattering geometries with full linear polarization analysis to unambiguously identify magnetic scattering contributions. At low temperatures, EuPtSi$_{\text{3}}$ stabilizes type A antiferromagnetism featuring various long-wavelength modulations. For magnetic fields applied in the hard magnetic basal plane, well-defined regimes of cycloidal, conical, and fan-like superstructures may be distinguished that encompass a pocket of commensurate type A order without superstructure. For magnetic field applied along the easy axis, the phase diagram comprises the cycloidal and conical superstructures only. Highlighting the power of polarized REXS, our results reveal a combination of magnetic phases that suggest a highly unusual competition between antiferromagnetic exchange interactions with Dzyaloshinsky--Moriya spin--orbit coupling of similar strength.
Izydor z Sewilli żyjący na przełomie VI/VII w. w wizygockiej Hiszpanii z jednej strony gromadził w swych dziełach dziedzictwo świata antycznego, z drugiej zaś stał się jedną z najważniejszych auctoritas średniowiecza. Żył w czasach przełomu historycznego, kulturowego, politycznego, a zmiana otaczającego świata zazwyczaj generuje zmiany językowe. Celem badań było sprawdzenie jak głoszone przez Izydora eksplicytnie poglądy na świętość wyrażoną przez leksem sanctus, mają się do tych immanentnie tkwiących w jego języku. W związku z tym przebadano pod kątem semantyki i źródeł trzy definicje sanctus zawarte w Etymologiach oraz dziele O różnicach słów, a następnie zestawiono je z tekstowymi wystąpieniami tego słowa w korpusie wszystkich dzieł Izydora o potwierdzonej autentyczności. Te ostatnie badano z zastosowaniem metod korpusowych, przy użyciu oprogramowania Sketch Engine. Dodatkowo jako tło analizy wykorzystano materiał leksykograficzny zawarty w kilku słownikach łaciny klasycznej i kościelnej. Wyniki wskazują na starożytną proweniencję znaczeń leksemu sanctus deklarowanych w izydorowych definicjach oraz odmienny, wyraźnie średniowieczny, eklezjalny profil semantyczny słowa w korpusie tekstów. Przeprowadzone badania ukazują proces adaptacji języka łacińskiego do zmieniających się okoliczności, przemiany pojęć i świata myśli pod wpływem chrześcijaństwa u progu średniowiecza u jednego z najważniejszych autorów tego okresu.

„Hyperborea” to pojęcie dobrze znane już badaczom starożytności. Porozmawiaj święta Północ biblijna, jako antyteza złowrogiej Północy Goga, jest dobrze do złaczom Biblii. Ten artykuł wyjścia za punkt wyjścia te dwie koncepcje. Jednak celem niniejszego artykułu jest skonfrontowanie biblijnej i antycznej wizji Północy z wybranymi źródymi patrystycznymi i średniowiecznymi. Chodzi o przedstawienie zmian w historycznym i geograficznym znaczeniu „Hyperborea”. Literatura grecka opisuje Hyperboreę jako raj leżący na najdalszych krańcach Północy. Pozornie ta wizja Północy się się być podobna do północnego raju w Biblii. Jednak literatura patrystyczna, która dobrze zna grecki mit o Hyperborejczykach, nie aplikuje żadnych dalszych analiz egzegetycznych. Hyperborea jest dla Ojców Kościoła „przedłużeniem” Scytii, a więc nie jest ona ona ani rajem, ani też idealną ziemią obiecaną. Jest ona odpowiedzią ekumeny i posiada wszystkie dobre i złe cechy terytorium, które zamieszkują zwykli ludzie. Hyperborea została przekształcona z greckiej krainy idealnej w historyczną, realnie wcześnie rzeczywistość. Nazwa ta wymagana jest podróżon do terytorium scytyjskiego, jak i do terenów leżących na północ od Scytii. Jednak rozwój horyzontu geograficznego przesuwał nieaktualne pojęcie „Hyperborea” coraz bardziej na północ. Linia tego horyzontu geograficznego wyznaczona w literaturze bizantyńskiej przez Teofanesa w VIII wieku i przez Nicefora Gregorasa w wieku XIV. Ten ostatni skazał na Ruś Moskiewską jako na leżącą na północnym-wschodzie chrześcijańską Hyperboreę. Taka sama linia geograficznego horyzontu w literaturze łacińskiej została bardzo delikatnie wskazana przez Adama z Bremy, który pisał o hyperborejskiej Skandynawii. Obok horyzontu geograficznego funkcjonował horyzontstricte literacki, gdzie dominował klasyczny topos, oparty na tekstach autorów klasycznych.

Extracting cause-effect entities from medical literature is an important task in medical information retrieval. A solution for solving this task can be used for compilation of various causality relations, such as, causality between disease and symptoms, between medications and side effects, between genes and diseases, etc. Existing solutions for extracting cause-effect entities work well for sentences where the cause and the effect phrases are name entities, single-word nouns, or noun phrases consisting of two to three words. Unfortunately, in medical literature, cause and effect phrases in a sentence are not simply nouns or noun phrases, rather they are complex phrases consisting of several words, and existing methods fail to correctly extract the cause and effect entities in such sentences. Partial extraction of cause and effect entities conveys poor quality, non informative, and often, contradictory facts, comparing to the one intended in the given sentence. In this work, we solve this problem by designing an unsupervised method for cause and effect phrase extraction, PatternCausality, which is specifically suitable for the medical literature. Our proposed approach first uses a collection of cause-effect dependency patterns as template to extract head words of cause and effect phrases and then it uses a novel phrase extraction method to obtain complete and meaningful cause and effect phrases from a sentence. Experiments on a cause-effect dataset built from sentences from PubMed articles show that for extracting cause and effect entities, PatternCausality is substantially better than the existing methods with an order of magnitude improvement in the F-score metric over the best of the existing methods.
AbstractThis essay tracks a brief history of the concept of ‘co-breathing’ or ‘conspiration’ (συμπνοία), from its initial conception in Stoic cosmology in the third century BCE to its appropriation in Christian thought at the end of the second century CE. This study focuses on two related strands: first, how the term gets associated anachronistically with two paradigmatic philosopher-physicians, Hippocrates and Pythagoras, by intellectuals in the Early Roman Empire; and second, how the same term provides the early Church Fathers with a means to synthesize and explain discrete notions of ‘breath’ (πνεῦμα) through a repurposing of the pagan concept. Sources discussed include figures associated with Stoic, Pythagorean, and early Christian cosmologies.
Tworząc "De ortu et obitu Patrum", Izydor nawiązuje do tradycji hagiograficznej, przejmując zarówno wypracowane przez nią wzorce kompozycyjne, jak też cele. Ułożone przez niego żywoty wybitnych biblijnych postaci w pierwszej kolejności służą zbudowaniu czytelnika. Funkcje perswazyjna, komunikacyjna i rekreacyjna wraz ze służebną wobec nich funkcją poetycką są z różnym natężeniem realizowane w różnych częściach relacji, prowadząc – zgodnie z konwencją przyjętą w hagiografii – ku realizacji dzieła zbawienia w życiu czytelnika. Odstępując od wymogów gatunku, Izydor przekazuje również informacje nieprzydatne do charakteryzacji prezentowanych postaci. Ich obecność w tekście świadczy o jego ciekawości świata, uniwersalistycznym spojrzeniu na dzieje oraz zmyśle natury, stanowi też o dodatkowej atrakcyjności utworu dla czytelnika.

Many approaches have been proposed for early classification of time series in light of its significance in a wide range of applications including healthcare, transportation and finance. However, recently a preprint saved on Arxiv claim that all research done for almost 20 years now on the Early Classification of Time Series is useless, or, at the very least, ill-oriented because severely lacking a strong ground. In this paper, we answer in detail the main issues and misunderstandings raised by the authors of the preprint, and propose directions to further expand the fields of application of early classification of time series.
The Covid-19 pandemic has caused a spur in the medical research literature. With new research advances in understanding the virus, there is a need for robust text mining tools which can process, extract and present answers from the literature in a concise and consumable way. With a DialoGPT based multi-turn conversation generation module, and BM-25 \& neural embeddings based ensemble information retrieval module, in this paper we present a conversational system, which can retrieve and answer coronavirus-related queries from the rich medical literature, and present it in a conversational setting with the user. We further perform experiments to compare neural embedding-based document retrieval and the traditional BM25 retrieval algorithm and report the results.

In this paper, we study the problem of early stopping for iterative learning algorithms in a reproducing kernel Hilbert space (RKHS) in the nonparametric regression framework. In particular, we work with the gradient descent and (iterative) kernel ridge regression algorithms. We present a data-driven rule to perform early stopping without a validation set that is based on the so-called minimum discrepancy principle. This method enjoys only one assumption on the regression function: it belongs to a reproducing kernel Hilbert space (RKHS). The proposed rule is proved to be minimax-optimal over different types of kernel spaces, including finite-rank and Sobolev smoothness classes. The proof is derived from the fixed-point analysis of the localized Rademacher complexities, which is a standard technique for obtaining optimal rates in the nonparametric regression literature. In addition to that, we present simulation results on artificial datasets that show the comparable performance of the designed rule with respect to other stopping rules such as the one determined by V-fold cross-validation.
Artykuł ukazuje proces powstawania struktury eklezjalnej w Ewangelii według św. Marka, począwszy od powstania pierwszej wspólnoty domowego Kościoła w oparciu o οἰκία Szymona i Andrzeja (por. Mk 1,29) do momentu spotkania w czasie pierwszego cudu rozmnożenia chlebów i ryb (por. Mk 6,34-44), podobnych wspólnot powstałych na terenie Galilei. Inspiracją do takiej interpretacji tej części Ewangelii według św. Marka był dla nas pierwszy zachowany komentarz do tejże Ewangelii autorstwa Hieronima ze Strydonu. Autor, komentując uzdrowienie niewidomego z Betsaidy (por. Mk 8,22-26), ukazał „dom” jako symbol Kościoła i przedstawił metodę interpretacji Pisma, dzięki której można tak odczytać przesłanie Ewangelii Marka.

The main recipients of the ADLOCVT COH and DECVRSIO sesterces were Roman soldiers. As part of the pay and occasional cash prizes, these coins were offered not only to the Praetorians or the soldiers of cohors Germanorum, but also to the legionnaires, the soldiers of the Auxilia and those who served in the fleet. Money played a vital role in the communication between the emperor and milites Romani. It was through the use of certain types of ideas and slogans that the ruler created his own image, e.g. as a trained horseman and a competent commander (vide DECVRSIO). In turn, by publicizing the fact that the emperor gave special speeches to the soldiers who participated in the military rallies (vide ADLOCVT COH) he could pursue the political goals that the current situation required, such as the restoration of the correct relations between Nero and the Praetorian soldiers after the failure of the Pisonian conspiracy. Emissions of the coins showing this type of encounter in the wider context always meant the “bond” of the emperor with the subordinates, which was certainly welcomed by them. Therefore, the use of the slogan adlocutio became a universal idea in the relations between the soldiers and the emperors of the Roman state.

An Early modeling approach of transistors characterized by simplicity and accuracy in representing intrinsic non-linearities is applied to the characterization of propagation delay and level transition switching properties of NPN and PNP small signal transistors. Eight types of devices were considered, each represented by 5 samples taken from the same lot, totaling 20 NPN and 20 PNP transistors. Four switching time measurements were experimentally obtained, and the transistors also had their Early parameters $V_a$ (the Early voltage) and $s$ (a proportionality constant such that $R_o = 1/tan(s I_B)$ accurately estimated by using an experimental-numeric procedure that involves Hough transform accumulation in order to identify the crossing of the base current ($I_B$) indexed characteristic isolines, yielding the respective $V_a$. The timing measurements exhibited strong positive Pearson correlations when taken pairwise. When these measurements were compared individually to the respective Early parameters, no significant Pearson correlation was obtained. However, a strong relationship was observed between the product of the two Early parameters and the ratio between the fall and rise time. A Pearson correlation coefficient of 0.78 was observed between these variables in the case of NPN devices. This suggests that transistors with larger average current gain tend to have more similar rise and fall times. The different relationship observed for PNP devices (Pearson 0.41) suggests some intrinsic difference in the way the Early parameters influence the rise and fall times of small signal transistors.
Early stopping of iterative algorithms is an algorithmic regularization method to avoid over-fitting in estimation and classification. In this paper, we show that early stopping can also be applied to obtain the minimax optimal testing in a general non-parametric setup. Specifically, a Wald-type test statistic is obtained based on an iterated estimate produced by functional gradient descent algorithms in a reproducing kernel Hilbert space. A notable contribution is to establish a "sharp" stopping rule: when the number of iterations achieves an optimal order, testing optimality is achievable; otherwise, testing optimality becomes impossible. As a by-product, a similar sharpness result is also derived for minimax optimal estimation under early stopping studied in [11] and [19]. All obtained results hold for various kernel classes, including Sobolev smoothness classes and Gaussian kernel classes.
Bipolar junction transistors (BJTs) have been at the core of linear electronics from its beginnings. Although their properties can be well represented transport model equations, design and analysis approaches have, to a good extent, been limited to using current-equispaced horizontal and parallel isolines of the characteristic surface. Here, we resort to the geometrical structure imposed on BJTs behavior by the Early effect and voltage as a means to derive a simple, intuitive and more complete respective model that, though excluding cut-off and saturation regimes, can simplify the design and characterization of BJTs and respective circuits, including integrated devices. The approach involves using a beam of isolines converging at the Early voltage as the model of a BJT. The angles of the isolines, another important aspect of BJTs, are experimentally verified often to vary almost in linear fashion with the base current, endowing the proposed Early model with an intrinsic geometric nature. An experimental-numerical methodology is suggested for the Early model estimation, and applied to 12 real-world small signal NPN BJTs. Interesting results are obtained, including the identification of diverse Early voltage values for different BJT types and the observation, for the considered BJTs, of the almost linear variation of the isoline angles with the input current. A case example of transfer function estimation, as well as total harmonic distortion analysis, are also provided in order to illustrate the potential of the proposed methodology for approximating, under certain circumstances, the operation of the common emitter configuration. The proposed model also has good potential as a didactic aid in physics and electronics programs, complementing the currently adopted modeling approaches.
This working paper unveils the crafting of a systematic literature review on open-source platforms. The high-competitive mobile devices market, where several players such as Apple, Google, Nokia and Microsoft run a platforms- war with constant shifts in their technological strategies, is gaining increasing attention from scholars. It matters, then, to review previous literature on past platforms-wars, such as the ones from the PC and game-console industries, and assess its implications to the current mobile devices platforms-war. The paper starts by justifying the purpose and rationale behind this literature review on open-source platforms. The concepts of open-source software and computer-based platforms were then discussed both individually and in unison, in order to clarify the core-concept of 'open-source platform' that guides this literature review. The detailed design of the employed methodological strategy is then presented as the central part of this paper. The paper concludes with preliminary findings organizing previous literature on open-source platforms for the purpose of guiding future research in this area.
