Mechanical Mechanism of Surrounding Rock Failure and Stability Control for Gob‐Side Entry Driving Near an Advancing Working Face

open access: yesEnergy Science &Engineering, EarlyView.
Taking the 5104 return airway of Checun Coal Mine as an example, this study visually summarises the main findings and methodologies of the research on surrounding rock control in gob‐side entry driving near an advancing working face. By establishing theoretical and numerical simulation analysis models, the stress distribution and plastic zone evolution

Progressive Curriculum Learning with Scale-Enhanced U-Net for Continuous Airway Segmentation [PDF]

open access: yesarXiv
Continuous and accurate segmentation of airways in chest CT images is essential for preoperative planning and real-time bronchoscopy navigation. Despite advances in deep learning for medical image segmentation, maintaining airway continuity remains a challenge, particularly due to intra-class imbalance between large and small branches and blurred CT ...

Study on Surrounding Rock Control Technology of Gob‐Gob Roadway Driven by Fully Mechanized Caving With Large Mining Height and Small Coal Pillar in Extra Thick Coal Seam

open access: yesEnergy Science &Engineering, EarlyView.
The analysis showed that the roof rock beam fractured above the side of the 5 m small coal pillar due to the influence of an anticline structure, leading to the proposal of an asymmetric control mechanism. Grouting pillars and individual supports were used for support, and the technology was successfully applied in the field, meeting the production ...

Therapeutic alternatives with CPAP in obstructive sleep apnea [PDF]

open access: yes, 2019
Obstructive Sleep Apnea (OSA), characterized by airflow cessation (apnea) or reduction (hypopnea) due to repeated pharyngeal obstructions during sleep, causes frequent disruption of sleep and hypoxic events. The condition is linked to many adverse health

Targeting the Tumor Microbiota in Cancer Therapy Basing on Nanomaterials

open access: yesExploration, EarlyView.
Intra‐tumoral microbiota, which is a potential component of the tumor microenvironment, has been emerging as a key participant and driving factor in cancer. This article reviews the latest progress in this field, including the microbial community within tumors and its pro‐cancer mechanisms, as well as the anti‐tumor strategies targeting intra‐tumoral ...

A rare case of pulmonary adenoid cystic carcinoma with liver metastases treated effectively with stereotactic body radiation therapy

open access: yesPrecision Radiation Oncology, Volume 6, Issue 4, Page 335-340, December 2022., 2022
Abstract Pulmonary adenoid cystic carcinoma (PACC) is an extremely rare neoplasm. Adenoid cystic carcinoma (ACC) usually occurs in the salivary glands of the head and neck. Given its rare occurrence, there are no established guidelines for the treatment of progressive and/or relapsed disease.
