Central obesity and blood pressure burden among Chinese children and adolescents with normal body mass index: a repeated-measures analysis of the China health and nutrition survey
Abstract Objective: Body mass index (BMI) is widely used to screen for pediatric adiposity, but it cannot differentiate fat distribution and fails to identify central fat accumulation among normal-weight youth. We aimed to evaluate whether central obesity was independently associated with high blood pressure among Chinese children and adolescents with normal BMI.
Wireless acoustic-driven current source achieving nanoampere-level at millimeter-scale
Abstract Piezoelectric surface acoustic wave devices can drive charge carriers in semiconductors through the acoustoelectric effect, generating direct currents with potential applications in sensing and biomedicine. However, current sources based on this mechanism that combine nanoampere-level precision, a wide dynamic range, and long-term operational stability have yet to be demonstrated.
POCUS-guided nasojejunal tube placement reduces malposition and radiation exposure in neonates: a multicenter real-world retrospective study
Abstract Blind nasojejunal tube (NJT) insertion with radiographic confirmation often results in initial malposition and repeated imaging in neonates, raising concerns about procedural delays and cumulative radiation. Point-of-care ultrasound (POCUS) enables real-time, radiation-free guidance, but multicenter neonatal evidence has been limited. We conducted a multicenter, real-world retrospective cohort study across three tertiary NICUs in China (May 2023–May 2025).

Nonreciprocal magnetoacoustic waves with out-of-plane phononic angular momenta
Abstract Surface acoustic wave (SAW) can carry phononic angular momentum, showing great potential as an energy-efficient way to control magnetism. Still, out-of-plane phononic angular momentum in SAW and its interaction with magnetism remain elusive. Here, we studied the SAW-induced magnetoacoustic waves and spin pumping in Ni-based films on LiNbO3 with selected SAW propagation direction.
Do Dual-Class Structures Help Stock Markets Attract Listings?
Financial globalization has allowed issuers more freedom to shop among jurisdictions and thus intensified stock market competition. Against this backdrop, the Hong Kong, Singapore, China, and UK stock markets have accepted the dual-class share structure (DCSS).
《英雄聯盟》LCK最快明年實施工資帽 | 英雄聯盟
原文：BLIX Future Of Salary Caps In League Of Legends Esports According to sources close to the BLIX'S editorial team, the LCK is set to implement a Salary Cap in the near future. Although the exact timing of the implementation cannot be confirmed, all indications point towards its full enforcement in the LCK as early as 2024. Regardless, a Salary Cap will, without a doubt, be implemented in the LCK.

Association between dietary inflammatory index and the risk of oral cancer in the southeast of China
Abstract Background/objectives To evaluate the role of the potential inflammatory effects of diet using the Energy adjusted Dietary Inflammatory Index (E-DII) for oral cancer. Subjects/methods A case-control study including 295 oral cancer cases and 425 controls from September 2010 to June 2018 was performed in Fujian Province, China. The E-DII was calculated based on the food frequency questionnaire (FFQ) and adjusted by total energy intake.
