Sustainable Upcycling of Office Waste Paper Into Cobalt/Carbon Aerogels for Highly Efficient Microwave Absorption

Electron, EarlyView.
Co/C aerogels (Co/CAs) are successfully fabricated with office waste paper (OWP) as the raw material by loading ZIF‐67 crystals. The optimal sample exhibited an effective absorption bandwidth of 5.6 GHz, which outperforms many biomass‐derived microwave absorbing materials.

A Deep Neural Network Based on Two‐Stage Training for Estimating Heart Rate Variability From Camera Videos

Health Care Science, EarlyView.
Heart Rate Variability Estimation from Camera Videos ABSTRACT Background Studies have shown that heart rate variability (HRV) is a predictor of the prognosis of cardiovascular diseases. Contact heartbeat monitoring equipment is widely used, especially in hospitals, and benefits from the rapidity and accuracy of the detection of physiological health ...

Deep learning–driven chromatic X‐ray imaging based on multicolor halide scintillation film stacks for quantitative densitometry

Information &Functional Materials, EarlyView.
The vapor‐deposited stacking strategy for multicolor halide scintillation films has been developed for chromatic X‐ray imaging, while enabling the systematic curation of a materials genome database. The effectiveness has been demonstrated through segmentation of complex circuit boards and 3D reconstruction of material density distributions.

Alexithymia in Schizophrenia and Psychosis Vulnerability: A Systematic Review and Meta‐Analysis

Journal of Clinical Psychology, Volume 81, Issue 6, Page 410-424, June 2025.
ABSTRACT Aims Disturbances involving impairments in experience and expression of affect are frequently identified in schizophrenia samples. Alexithymia underlies cognitive impairments in identification and expression of affect, further implicated in affect dysregulation.

Comparison of the SMI Technique and CEUS for the Assessment of Microvasculature in Leiomyosarcoma and Its Clinical Value for Application

Journal of Clinical Ultrasound, EarlyView.
SMI and CEUS can clearly reflect the microvascular situation in fibroids and effectively guide the clinical treatment of patients with uterine fibroids, but the effect of SMI is better than that of CEUS in guiding the treatment of patients, which can provide a reference for the selection of clinical treatment programs.
