Predicting breast cancer response to neoadjuvant chemotherapy with ultrasound-based deep learning radiomics models —— dual-center study

open access: yesBMC Cancer
Purpose The aim of this study is to develop and validate a deep learning fusion model based on early (two-cycle) ultrasound images, using stacking fusion technology for the intratumoral and peritumoral regions, to predict early tumor response in breast ...

Diagnostic significance of combined two-dimensional ultrasound and three-dimensional tomographic ultrasound imaging for cleft palate in fetus of 11–13 + 6 weeks: a prospective study

open access: yesThe Journal of Maternal-Fetal & Neonatal Medicine
Purpose Clinical screening for cleft palate in fetus currently focuses on weeks 20–24. It has been shown that cleft palate can be detected by ultrasound in first-trimester anatomy scan, but there are no large-scale samples to validate.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Assessment of fetal left ventricular function in pregnancies with Anti-Ro/SSA or Anti-La/SSB antibodies using velocity vector imaging

open access: yesBMC Pregnancy and Childbirth
Background Intrauterine exposure to anti SSA/Ro and anti SSB/La antibodies has been associated with the development of fetal congenital heart block and, in severe cases, fetal demise.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
