Japan is one of many locations in Asia where Chinese companies access American AI chips -- by renting hardware that's owned by foreign firms and installed in overseas data centers. Taiwan prosecutors suspect that three individuals successfully smuggled at least one shipment of Nvidia artificial intelligence chips to China after first exporting them to Japan, people familiar with the matter said. The trio was detained last week by Taiwan's Keelung District Prosecutors Office for allegedly falsifying documents related to exports of Super Micro Computer servers containing advanced Nvidia chips, which the U.S. has barred from sale to China without a license from Washington. The move marked the island democracy's first public crackdown on AI chip diversion after years of pressure from the U.S. to take a more active role in curtailing China's tech access. When Taiwan authorities apprehended the three defendants -- who've now been officially detained -- they also seized about 50 servers for which they accuse the trio of preparing fraudulent export documents. But at least one shipment had already gone through Taiwan customs, according to the people familiar with the matter, who requested anonymity to speak about an ongoing criminal investigation.

China launches new military exercises around Taiwan following record $11.1 billion U.S. arms sale, with warships conducting live-fire drills that could escalate toward war.

Building fires pose a persistent threat to life, property, and infrastructure, emphasizing the need for advanced risk mitigation strategies. This study presents a data-driven framework analyzing U.S. fire risks by integrating over one million fire incident reports with diverse fire-relevant datasets, including social determinants, building inventories, weather conditions, and incident-specific factors. By adapting machine learning models, we identify key risk factors influencing fire occurrence and consequences. Our findings show that vulnerable communities, characterized by socioeconomic disparities or the prevalence of outdated or vacant buildings, face higher fire risks. Incident-specific factors, such as fire origins and safety features, strongly influence fire consequences. Buildings equipped with fire detectors and automatic extinguishing systems experience significantly lower fire spread and injury risks. By pinpointing high-risk areas and populations, this research supports targeted interventions, including mandating fire safety systems and providing subsidies for disadvantaged communities. These measures can enhance fire prevention, protect vulnerable groups, and promote safer, more equitable communities.

Artifact removal in electroencephalography (EEG) is a longstanding challenge that significantly impacts neuroscientific analysis and brain-computer interface (BCI) performance. Tackling this problem demands advanced algorithms, extensive noisy-clean training data, and thorough evaluation strategies. This study presents the Artifact Removal Transformer (ART), an innovative EEG denoising model employing transformer architecture to adeptly capture the transient millisecond-scale dynamics characteristic of EEG signals. Our approach offers a holistic, end-to-end denoising solution for diverse artifact types in multichannel EEG data. We enhanced the generation of noisy-clean EEG data pairs using an independent component analysis, thus fortifying the training scenarios critical for effective supervised learning. We performed comprehensive validations using a wide range of open datasets from various BCI applications, employing metrics like mean squared error and signal-to-noise ratio, as well as sophisticated techniques such as source localization and EEG component classification. Our evaluations confirm that ART surpasses other deep-learning-based artifact removal methods, setting a new benchmark in EEG signal processing. This advancement not only boosts the accuracy and reliability of artifact removal but also promises to catalyze further innovations in the field, facilitating the study of brain dynamics in naturalistic environments.

Word sense disambiguation primarily addresses the lexical ambiguity of common words based on a predefined sense inventory. Conversely, proper names are usually considered to denote an ad-hoc real-world referent. Once the reference is decided, the ambiguity is purportedly resolved. However, proper names also exhibit ambiguities through appellativization, i.e., they act like common words and may denote different aspects of their referents. We proposed to address the ambiguities of proper names through the light of regular polysemy, which we formalized as dot objects. This paper introduces a combined word sense disambiguation (WSD) model for disambiguating common words against Chinese Wordnet (CWN) and proper names as dot objects. The model leverages the flexibility of a gloss-based model architecture, which takes advantage of the glosses and example sentences of CWN. We show that the model achieves competitive results on both common and proper nouns, even on a relatively sparse sense dataset. Aside from being a performant WSD tool, the model further facilitates the future development of the lexical resource.

There is great interest in developing radiological classifiers for diagnosis, staging, and predictive modeling in progressive diseases such as Parkinson's disease (PD), a neurodegenerative disease that is difficult to detect in its early stages. Here we leverage severity-based meta-data on the stages of disease to define a curriculum for training a deep convolutional neural network (CNN). Typically, deep learning networks are trained by randomly selecting samples in each mini-batch. By contrast, curriculum learning is a training strategy that aims to boost classifier performance by starting with examples that are easier to classify. Here we define a curriculum to progressively increase the difficulty of the training data corresponding to the Hoehn and Yahr (H&Y) staging system for PD (total N=1,012; 653 PD patients, 359 controls; age range: 20.0-84.9 years). Even with our multi-task setting using pre-trained CNNs and transfer learning, PD classification based on T1-weighted (T1-w) MRI was challenging (ROC AUC: 0.59-0.65), but curriculum training boosted performance (by 3.9%) compared to our baseline model. Future work with multimodal imaging may further boost performance.

The Industrial Development Bureau of the Ministry of Economic Affairs has led the "Smart City Taiwan" project in response to the government's goal to promote industrial upgrading and transformation and smart technologies. Through public-private-people partnership mechanism, the Smart City Taiwan project utilizes smart technologies to drive smart services (healthcare, governance/safety, transportation, agriculture, education, and tourism and retail) in 22 cities/countries across Taiwan. As of today, about 300 businesses have participated in the project, offering 223 smart services to 8.54 million people. These smart services have successfully solved the pain points of the general public and have also been introduced to foreign countries. For young children, a variety of stimulant interactions can be triggers for learning.
