Breast Cancer Diagnosis Using a Dual-Modality Complementary Deep Learning Network With Integrated Attention Mechanism Fusion of B-Mode Ultrasound and Shear Wave Elastography.

Objective: To develop and evaluate a Dual-modality Complementary Feature Attention Network (DCFAN) that integrates spatial and stiffness information from B-mode ultrasound and shear wave elastography (SWE) for improved breast tumor classification and axillary lymph node (ALN) metastasis prediction.

Methods: A total of 387 paired B-mode and SWE images from 218 patients were retrospectively analyzed. The proposed DCFAN incorporates attention mechanisms to effectively fuse structural features from B-mode ultrasound with stiffness features from SWE.

Find Hidden Modality Divergence: Adversarial Aware Learning for Unsupervised Visible-Infrared Person Re-Identification.

Unsupervised visible-infrared person re-identifi-cation (Unsupervised VI-ReID) aims to learn discriminative identity features under the large modality gap without any labeled data. Currently, the state-of-the-art methods optimize cross-modality differences by using contrastive learning as the underlying paradigm. However, they neglect the problem of modality divergence during the cross-modality optimization process.

A prior knowledge-supervised fusion network predicts survival after radiotherapy in patients with advanced gastric cancer.

Background And Objective: Predicting overall survival (OS) for advanced gastric cancer patients after radiotherapy is critical for developing an individualized treatment plan. However, existing studies have focused on gastric cancer CT images with a large amount of redundant information, neglecting the role of physicians' prior knowledge in guiding gastric cancer CT image information. We propose a multimodal fusion method based on prior knowledge to predict OS after radiotherapy in advanced gastric cancer patients to assist physicians in clinical diagnosis and treatment.

Corneal stromal lenticule transplantation for covering macular hole during vitrectomy.

Aim: To describe an innovative surgical technique for pathologic myopia and macular holes accompanied by retinal detachment using allogeneic corneal stromal lenticule transplantation combined with pars plana vitrectomy.

After pars plana vitrectomy, an allogeneic corneal stromal lenticule was thawed, trimmed into approximately 60 µm thick and 100 µm larger than the macular hole and transferred to cover the macular hole through the trocar.

In-situ signal amplification of microneedles in a transistor for allergy molecular detection.

The rapid and accurate detection of histamine is of great significance for the early diagnosis and precise treatment of allergic diseases. Traditional histamine detection usually is more invasive and limited for the detection of allergic reactions in local areas. In this work, microneedles (MNs) enable of in-situ transdermal detection are employed as the extended gate of the thin-film transistor (TFT).

Gravitational wave astronomy with TianQin.

The opening of the gravitational wave window has significantly enhanced our capacity to explore the Universe's most extreme and dynamic sector. In the mHz frequency range, a diverse range of compact objects, from the most massive black holes at the farthest reaches of the Universe to the lightest white dwarfs in our cosmic backyard, generate a complex and dynamic symphony of gravitational wave signals. Once recorded by gravitational wave detectors, these unique fingerprints have the potential to decipher the birth and growth of cosmic structures over a wide range of scales, from stellar binaries and stellar clusters to galaxies and large-scale structures.

Nonlocalized Conductive Paths Construction and In-depth Mechanism Analysis for the Robust Resistive Switching in Halide Perovskites.

The conductive paths (CPs) established by defects in halide perovskites (HPs) tend to be disrupted under external influences, leading to deterioration of their RRAM performances. Here we propose an effective strategy to enhance the CPs in HP RRAMs by doping Ag to partially substitute Pb in MAPbI, which facilitates the nonlocalized growth of Ag CPs and thereby improves the stability of CPs. The optimal doped device demonstrates excellent RRAM performances including high ON/OFF ratios (>10), long retention (>10 s), large endurance (>10 cycles), uniform parameters, and excellent yield.

A Virtual-Sensor Construction Network Based on Physical Imaging for Image Super-Resolution.

Image imaging in the real world is based on physical imaging mechanisms. Existing super-resolution methods mainly focus on designing complex network structures to extract and fuse image features more effectively, but ignore the guiding role of physical imaging mechanisms for model design, and cannot mine features from a physical perspective. Inspired by the mechanism of physical imaging, we propose a novel network architecture called Virtual-Sensor Construction network (VSCNet) to simulate the sensor array inside the camera.

The highly crosslinked network allows for high resistance to organic solvents and high breakdown strength over 2 MV cm.

SERS detection of uranyl based on MOF-coated gold nanooctahedron hybrid.

The ability to sensitively and quantitatively detect uranyl in complex samples plays a vital role in environmental monitoring. In this work, an MOF-coated gold (Au) nanohybrid was synthesized for uranyl detection by surface-enhanced Raman scattering (SERS) technology. The MOF shell not only prevents the Au nanoparticles from rapid aggregation, but also effectively enhances the Raman signal of uranyl.

A Hydrogel-coated Wood Membrane with Intelligent Oil Pollution Detection for Emulsion Separation.

Considering the potential threats posed by oily wastewater to the ecosystem, it is urgently in demand to develop efficient, eco-friendly, and intelligent oil/water separation materials to enhance the safety of the water environment.

The size of the P-CP membrane can be customized to meet specific requirements.

[Effect of traditional Chinese medicine in attenuating chronic kidney disease and its complications by regulating gut microbiota-derived metabolite trimethylamine N-oxide: a review].

Trimethylamine N-oxide(TMAO), a metabolite of gut microbiota, is closely associated with chronic kidney disease(CKD). It can aggravate the kidney injury and promote the occurrence of complications of CKD mainly by inducing renal fibroblast activation, vascular endothelial inflammation, macrophage foaming, platelet hyperreactivity, and inhibition of reverse cholesterol transport. Thus it is of great significance for clinical treatment of CKD to regulate circulating TMAO and alleviate its induced body damage.
