Two types of detectors (GC 4018 and BE 5030) were compared regarding the signal from the outer dead layer of the detector. Gamma-spectra of Am-241 were acquired with various delays against the starting signal from an alpha LS probe. Coincidence spectra from both detectors were different. The dead-layer signal does not increase the full-energy peak efficiency but it increases the total efficiency, as it was demonstrated by the reconstruction of Am-241 spectra for both detectors.

Background: Research demonstrates that Point-of-care ultrasound (POCUS) improves clinical outcomes for patients. Improving clinician satisfaction with POCUS should promote utilization into everyday practice, leading to improved clinical outcomes. Despite this benefit, there are still barriers to use including POCUS workflow.

Background: Preserving plant genetic resources is essential for tackling global food security challenges. Effectively meeting future agricultural demands requires comprehensive and efficient assessments of genetic diversity in breeding programs and germplasm from gene banks. This research investigated the diversity of pheno-morphological traits, along with the fatty acid and tocopherol content and composition, in 135 double haploid lines of camelina.

Background: Identifying markers or genes crucial for growth traits in Zhongwei goats is pivotal for breeding. Pinpointing genetic factors linked to body size gain enhances breeding efficiency and economic value. In this study, we used the MGISEQ-T7 platform to re-sequence 240 Zhongwei goats (133 male; 107 female) belonging to 5 metrics of growth traits at different growth stages (40 days and 6 months, here in after referred to as 40d and 6 m), namely, Body Weight (BW), Body Height (BH), Body Length (BL), Chest Circumference (CC), Tube Circumference (TC) were examined.

Department of Spinal Surgery, The Third Hospital of Hebei Medical University, No.139 Ziqiang Road, Shijiazhuang, 050051, Hebei, P.R. China.
Objective: This study aimed to compare the use of the endoscopic drill (ED) with the extra-endoscopic trephine (EET) in treating lumbar disc herniations with regard to efficiency, safety, and clinical outcomes.
Methods: From January 2022 and June 2023, 136 patients who had the single-level LDH and received the transforaminal endoscopic surgery were divided into two groups according to the foraminoplasty technique: the EET group (n = 69) and the ED group (n = 67). Surgery-related parameters, complications, Visual Analogue Scale (VAS, 0-10), and Oswestry Disability Index (ODI, 0-100%) were assessed and compared among two groups.
Reverse design of broadband sound absorption structure based on deep learning method.
Sci Rep

School of Mechanical and Automotive Engineering, Shanghai University of Engineering Science, Shanghai, 201620, China.
This research presents a method based on deep learning for the reverse design of sound-absorbing structures. Traditional methods require time-consuming individual numerical simulations followed by cumbersome calculations, whereas the deep learning design method significantly simplifies the design process, achieving efficient and rapid design objectives. By utilizing deep neural networks, a mapping relationship between structural parameters and the sound absorption coefficient curve is established.
