DenseKD: Dense Knowledge Distillation by Exploiting Region and Sample Importance.

Knowledge distillation (KD) can compress deep neural networks (DNNs) by transferring the knowledge of the redundant teacher model to the resource-friendly student model, where cross-layer KD (CKD) conducts KD between each stage of students and the multiple stages of teachers. However, previous CKD schemes select the coarse-grained stagewise features of teachers to teach students, leading to improper channel alignment. Also, most of these methods conduct uniform distillation for all the knowledge, limiting students to focus more on important knowledge.

Silymarin mediates the gut-liver axis pathway to alleviate Carassius auratus hepatic lipid metabolism disorders caused by carbonate exposure.

Online identification of potential antioxidant components and evaluation of DNA oxidative damage protection ability in Prunus persica flowers.

A high performance liquid chromatography-ultraviolet-visible detector-electrospray ionization-ion trap-time-of-flight-mass spectrometry-total antioxidant capacity determination (HPLC-UVD-ESI-IT-TOF-MS-TACD) new online technique was developed for efficient screening of potential antioxidant active components in Prunus persica flowers (PPF) from 4 origins. Through this online system, 46 compounds were initially identified, while 20 compounds with DPPH binding activity and 21 compounds with FRAP binding activity were detected. The antioxidant activities of 9 compounds obtained from the screening were then validated in DNA oxidative damage protection study.

NaSb Alloy-Based Low-Frequency Mechanical Energy Harvesters for Virtual Taste Sensations.

Batteries can be activated by external mechanical force and generate current, enabling a smart class of electrochemical-mechanical strain energy harvesters therefrom. Here, we have developed a NaSb alloy-based harvester that is able to electrochemically convert low-frequency bending or pressing mechanical energy into electrical energy. The device is designed as a flexible symmetric cell incorporating two sodiated antimony nanoflake electrodes, whose peak power and energy output are more than twice those of other sodium-alloyed electrochemical-mechanical strain energy harvesters reported.

Removal of a pulmonary artery foreign body during pulse ablation in a patient with atrial fibrillation: A case report.

Background: Foreign bodies in the pulmonary circulation have been documented in the literature and are typically caused by interventional procedures. However, reports of pulmonary artery foreign bodies during femoral vein puncture are rare, and there is no description of this complication from the guidewire surface flows into the pulmonary artery during a pulse ablation in a patient with atrial fibrillation.

Case Summary: We described a case in which a linear foreign body suddenly appeared on fluoroscopy image during pulsed ablation of atrial fibrillation.

RepCo: Replenish sample views with better consistency for contrastive learning.

Contrastive learning methods aim to learn shared representations by minimizing distances between positive pairs, and maximizing distances between negative pairs in the embedding space. To achieve better performance of contrastive learning, one of the key problems is to design appropriate sample pairs. In most previous works, random cropping on the input image is utilized to obtain two views as positive pairs.

Development of an online UPLC-PDA-ESI-Q-TOF-MS-LOX-FLD system for rapid screening of anti-inflammatory compounds in Polygala tenuifolia Willd.

In this study, the first ultra-high performance liquid chromatography-photo-diode array-electrospray ionization-quadrupole-time-of-flight-mass spectrometry-lipoxygenase-fluorescence detector (UPLC-PDA-ESI-Q-TOF-MS-LOX-FLD) online system was developed for the identification and evaluation of anti-inflammatory active ingredients in Polygala tenuifolia Willd. Using this system, the UPLC fingerprints, mass fragments and LOX-binding peak profiles in the samples were rapidly and simultaneously obtained. A total of 101 compounds were isolated and identified and 38 compounds (11 oligosaccharide esters, nine xanthones, 17 saponins, and one glycosyloxyflavone) showed strong LOX-binding activity.

ICT literacy, resilience and online learning self-efficacy between Chinese rural and urban primary school students.

In the process of large-scale online education during the COVID-19 pandemic, students' online learning has caused widespread public concerns. This study investigated the relationships between Chinese rural and urban primary school students' information communications technology (ICT) literacy, student resilience, and online learning self-efficacy in a large-scale online education environment during the pandemic in China. We compared 5,037 primary school students in rural areas to 5,045 primary school students in urban areas with matching gender and grade in nine regions in China's Guangdong province, using a survey comprising an ICT literacy scale, a student resilience scale, an online learning self-efficacy scale, and an ICT devices scale.
