Design, Implementation and Environmental Impact of Cutoff Wall for Pollution Control in an Industrial Legacy Site.
Toxics
December 2024
Zhejiang Zone-King Environmental Sci & Tech Co., Ltd., Hangzhou 310064, China.
Heavy metal-organic pollutants compound pollution at industrial legacy sites and have caused damage to the ecological environment and human health during recent decades. In view of the difficulty and high cost of post-contamination remediation, it is worth studying, and practically applying, cutoff walls to reduce the spread of pollution in advance. In this study, field-scale studies were carried out at e-waste dismantling legacy sites in Taizhou, Zhejiang Province of China, through the process of site investigation, numerical simulation, and cutoff wall practical application.

Background: With increasing evidence supporting three-dimensional (3D) automated breast (AB) ultrasound (US) for supplemental screening of breast cancer in increased-risk populations, including those with dense breasts and in limited-resource settings, there is an interest in developing more robust, cost-effective, and high-resolution 3DUS imaging techniques. Compared with specialized ABUS systems, our previously developed point-of-care 3D ABUS system addresses these needs and is compatible with any conventional US transducer, which offers a cost-effective solution and improved availability in clinical practice. While conventional US transducers have high in-plane resolution (axial and lateral), their out-of-plane resolution is constrained by the poor intrinsic elevational US resolution.

To explore the surgical methods and treatment outcomes of nasal endoscopic surgery for nasal deformity secondary to unilateral cleft lip and palate, combined with nasal septal deviation, using nasal septal cartilage and bone. Eleven patients who underwent surgical treatment for unilateral cleft lip and palate secondary to nasal deformity in the Department of Otorhinolaryngology, Head and Neck Surgery, Linyi People's Hospital, Shandong Second Medical University, from March 2021 to March 2023, were retrospectively analyzed. The cohort included 8 males and 3 females, aged (22.

J Comput Neurosci
January 2025
Program in Neuroscience, Indiana University Bloomington, Bloomington, IN, USA.
Hippocampal representations of space and time seem to share a common coding scheme characterized by neurons with bell-shaped tuning curves called place and time cells. The properties of the tuning curves are consistent with Weber's law, such that, in the absence of visual inputs, width scales with the peak time for time cells and with distance for place cells. Building on earlier computational work, we examined how neurons with such properties can emerge through self-supervised learning.

Department of Ultrasound, Yiwu City Dermatology Hospital, Yiwu, China.
Background: Current treatments for non-suppurative sternoclavicular arthritis mainly include conservative therapy and surgery. For patients who are unresponsive to conservative treatment and unwilling to undergo surgery, ultrasound-guided intra-articular drug injections offer a minimally invasive alternative. Due to the lack of efficacy evaluation for this therapy, this study aims to objectively assess the effectiveness and safety of this treatment method.
