An Innovative Experimental Design for Measuring a Liquid Viscous Coefficient by a Falling Ball Method
Physics experiments outside the traditional laboratory using common materials have significantly contributed to physics education, especially during the global pandemic.1 They not only boost students’ interest and hands-on skills, but also encourage creativity and design abilities. Viscosity characterizes a liquid’s internal friction, and numerous general routes can be used for its measurement.2 Among them, the falling ball method is popular and requires balls, containers, and timing devices.

Chiral multimodal nanoprobes for sensing of biomarkers
Abstract Biomarker detection for early disease diagnosis demands materials with high sensitivity and anti-interference capability. However, conventional single-signal nanosensors often fail in complex biological matrices due to autofluorescence and matrix interference. Here, to address these challenges, we report the synthesis of chiral multimodal nanoprobes that integrate circular dichroism, fluorescence and magnetic resonance signals.

Chromosome-scale assembly of Artemia tibetiana genome, first aquatic invertebrate genome from Tibet Plateau - Scientific Data
Abstract Genomic-level studies on the adaptive evolution of animals in the Qinghai-Tibet Plateau have been rapidly increasing. However, most studies are concentrated on vertebrates, and there are few reports on invertebrates. Here, we report the chromosome-level genome assembly for the brine shrimp Artemia tibetiana from Kyêbxang Co, a high-altitude (4620 m above sea level) salt lake on the plateau, based on the combination of Illumina, Nanopore long-reads and Hi-C sequencing data.

An fMRI dataset in response to large-scale short natural dynamic facial expression videos - Scientific Data
Abstract Facial expression is among the most natural methods for human beings to convey their emotional information in daily life. Although the neural mechanisms of facial expression have been extensively studied employing lab-controlled images and a small number of lab-controlled video stimuli, how the human brain processes natural dynamic facial expression videos still needs to be investigated.

Brain Functional Representation of Highly Occluded Object Recognition
1. Introduction In recent years, with the emergence of deep learning, computer vision algorithms have demonstrated the ability to handle simple object recognition tasks [1]. However, accurate recognition faces significant challenges when the objects are highly occluded. These challenges primarily stem from information loss, where critical contextual information is missing due to occlusion, making it difficult for algorithms to accurately detect and recognize objects [2].

A Mixed Visual Encoding Model Based on the Larger-Scale Receptive Field for Human Brain Activity
4.1. The ERF and the Convolutional Kernel Size Based on the experimental data, it can be found that the mixed model that mixes RepLKNet and VGG16 achieves better encoding performance than ordinary VGG16 or ResNet. The possible reasons are discussed and analyzed as follows. The ERF size of traditional CNN networks can be increased in several ways. One option is to stack more layers and make the network deeper, thus theoretically increasing the size of the receptive field linearly.
