X-PARADE: Cross-Lingual Textual Entailment and Information Divergence across Paragraphs
Understanding when two pieces of text convey the same information is a goal
touching many subproblems in NLP, including textual entailment and
fact-checking. This problem becomes more complex when those two pieces of text
are in different languages. Here, we introduce X-PARADE (Cross-lingual
Paragraph-level Analysis of Divergences and Entailments), the first
cross-lingual dataset of paragraph-level information divergences. Annotators
label a paragraph in a target language at the span level and evaluate it with
respect to a corresponding paragraph in a source language, indicating whether a
given piece of information is the same, new, or new but can be inferred. This
last notion establishes a link with cross-language NLI. Aligned paragraphs are
sourced from Wikipedia pages in different languages, reflecting real
information divergences observed in the wild. Armed with our dataset, we
investigate a diverse set of approaches for this problem, including classic
token alignment from machine translation, textual entailment methods that
localize their decisions, and prompting of large language models. Our results
show that these methods vary in their capability to handle inferable
information, but they all fall short of human performance

WiCE: Real-World Entailment for Claims in Wikipedia
Textual entailment models are increasingly applied in settings like
fact-checking, presupposition verification in question answering, or summary
evaluation. However, these represent a significant domain shift from existing
entailment datasets, and models underperform as a result. We propose WiCE, a
new fine-grained textual entailment dataset built on natural claim and evidence
pairs extracted from Wikipedia. In addition to standard claim-level entailment,
WiCE provides entailment judgments over sub-sentence units of the claim, and a
minimal subset of evidence sentences that support each subclaim. To support
this, we propose an automatic claim decomposition strategy using GPT-3.5 which
we show is also effective at improving entailment models' performance on
multiple datasets at test time. Finally, we show that real claims in our
dataset involve challenging verification and retrieval problems that existing
models fail to address.Comment: EMNLP 202
SuperJunction cascode, a configuration to break the silicon switching frequency limit
This paper evaluates the SuperJunction MOSFET in cascode configuration with a low-voltage silicon MOSFET. The structure combines the good switching performance provided by the cascode configuration with advantages of the silicon technology as the robustness, the maturity and the low-cost. The objective of this paper is to elucidate and to demonstrate the reduction of switching losses of SuperJunction MOSFETs in cascode configuration with respect to their standalone counterparts (directly driven). A detailed simulation analysis of power loss contributions is carried out under hard-switching operation. Eventually, experimental evidence is provided by using a boost converter (100 V-to-400 V) in continuous conduction mode for a wide range of switching frequency (100 kHz-to-400 kHz) and output power (180W-to-500W).This work has been supported by the Spanish Government under Project MINECO-13-DPI2013-47176-C2-2-R, MINECO-15-DPI2014-56358-JIN, the scholarship FPU14/03268 and the Principality of Asturias under the grants âSevero Ochoaâ BP14-140 and by the Project FC-15- GRUPIN14-143 and by European Regional Development Fund (ERDF) grants
Lil-Bevo: Explorations of Strategies for Training Language Models in More Humanlike Ways
We present Lil-Bevo, our submission to the BabyLM Challenge. We pretrained
our masked language models with three ingredients: an initial pretraining with
music data, training on shorter sequences before training on longer ones, and
masking specific tokens to target some of the BLiMP subtasks. Overall, our
baseline models performed above chance, but far below the performance levels of
larger LLMs trained on more data. We found that training on short sequences
performed better than training on longer sequences.Pretraining on music may
help performance marginally, but, if so, the effect seems small. Our targeted
Masked Language Modeling augmentation did not seem to improve model performance
in general, but did seem to help on some of the specific BLiMP tasks that we
were targeting (e.g., Negative Polarity Items). Training performant LLMs on
small amounts of data is a difficult but potentially informative task. While
some of our techniques showed some promise, more work is needed to explore
whether they can improve performance more than the modest gains here. Our code
is available at https://github.com/venkatasg/Lil-Bevo and out models at

Fecal sacs attract insects to the nest and provoke an activation of the immune system of nestlings
Background: Nest sanitation is a widespread but rarely studied behavior in birds. The most common form of nest
sanitation behavior, the removal of nestling feces, has focused the discussion about which selective pressures
determine this behavior. The parasitism hypothesis, which states that nestling fecal sacs attract parasites that
negatively affect breeding birds, was proposed 40 years ago and is frequently cited as a demonstrated fact. But,
to our knowledge, there is no previous experimental test of this hypothesis.
Results: We carried out three different experiments to investigate the parasitism hypothesis. First, we used
commercial McPhail traps to test for the potential attraction effect of nestling feces alone on flying insects. We
found that traps with fecal sacs attracted significantly more flies (Order Diptera), but not ectoparasites, than the
two control situations. Second, we used artificial blackbird (Turdus merula) nests to investigate the combined
attraction effect of feces and nest materials on arthropods (not only flying insects). Flies, again, were the only
group of arthropods significantly attracted by fecal sacs. We did not detect an effect on ectoparasites. Third, we
used active blackbird nests to investigate the potential effect of nestling feces in ecto- and endoparasite loads
in real nestlings. The presence of fecal sacs near blackbird nestlings did not increase the number of louse flies or
chewing lice, and unexpectedly reduced the number of nests infested with mites. The endoparasite prevalence was
also not affected. In contrast, feces provoked an activation of the immune system as the H/L ratio of nestlings living
near excrements was significantly higher than those kept under the two control treatments.
Conclusions: Surprisingly, our findings do not support the parasitism hypothesis, which suggests that parasites are not
the main reason for fecal sac removal. In contrast, the attraction of flies to nestling feces, the elevation of the immune
response of chicks, and the recently described antimicrobial function of the mucous covering of fecal sacs suggest that
microorganisms could be responsible of this important form of parental care behavior (microbial hypothesisPeer reviewe
