Background/Objectives: This study compares clinical and radiological outcomes of open microscopic posterior cervical foraminotomy (PCF) and biportal endoscopic spine surgery (BESS) PCF in multi-level cases. While BESS PCF is effective in single-level surgeries, its role in multi-level procedures remains unclear. Methods: This retrospective cohort study included 60 patients treated for cervical radiculopathy from 2016 to 2023, divided into two groups, open microscopic PCF (Group M, n = 30) and BESS PCF (Group B, n = 30). Clinical outcomes were assessed using visual analogue scale (VAS) scores for neck and arm pain and the neck disability index (NDI). Radiological parameters included cervical angle, segmental angle, range of motion (ROM), and the extent of facetectomy. Results: Both groups showed improvement in the arm pain VAS and the NDI. However, Group B exhibited significantly better neck pain on the VAS at the final follow-up (p = 0.03). Radiologically, Group B maintained lordotic cervical and segmental angles postoperatively, while Group M showed kyphotic changes (p < 0.01). Segmental ROM was larger in Group M, indicating greater instability (p < 0.01). Group B had less extensive facetectomy while achieving comparable foraminal enlargement. Operative time was longer for Group B (p < 0.001). Conclusions: BESS PCF preserves cervical stability and reduces postoperative neck pain compared to open microscopic PCF in multi-level procedures. Despite longer operative times, its benefits in minimizing instability make it a promising option for treating multi-level cervical radiculopathy. Further research with long-term follow-up is recommended. [ABSTRACT FROM AUTHOR]

Increased demands for technological integration in higher education have resulted in new forms of course instruction. Under a flipped approach, students learn course materials outside the classroom while active learning methods are employed inside. This study focuses on the perceived effects of flipped instruction on knowledge acquisition in undergraduate students using information communication, accessibility, stimulation, interaction, and accumulation as measures. Undergraduate students indicated positive effects of flipped teaching and students' perceived learning improved as time spent using learning management systems increased. While knowledge acquisition tended to increase in most students, technological incompatibilities prevented the flipped approach from being fully accepted.

Porous pure SnO2 nanofibers (NFs) and La2O3 nanoparticles (NPs)-embedded porous SnO2 NFs were successfully synthesized via electrospinning followed by calcination. These materials were systematically evaluated as gas-sensing elements in metal-oxide-semiconductor (MOS) sensors. The La2O3 NPs embedded in porous SnO2 NFs demonstrated superior gas-sensing performance compared to pure SnO2 NFs. Specifically, the incorporation of La2O3 resulted in a 12-fold enhancement in gas-sensing response towards ethanol, significantly improving both sensitivity and selectivity by tuning the carrier concentration and modifying oxygen deficiencies and chemisorbed oxygen levels. Thus, La2O3 NPs embedded in SnO2 NFs present a promising strategy for the development of high-performance ethanol gas sensors. [ABSTRACT FROM AUTHOR]

This work reports on the development of an analyte sampling strategy on a plasmonic substrate to amplify the detection capability of a dual analytical system, paper spray ionization–mass spectrometry (PSI-MS) and surface-enhanced Raman spectroscopy (SERS). While simply applying only an analyte solution to the plasmonic paper results in a limited degree of SERS enhancement, the introduction of plasmonic gold nanoparticles (AuNPs) greatly improves the SERS signals without sacrificing PSI-MS sensitivity. It is initially revealed that the concentration of AuNPs and the type of analytes highly influence the SERS signals and their variations due to the "coffee ring effect" flow mechanism induced during sampling and the degree of the interfacial interactions (e.g., van der Waals, electrostatic, covalent) between the plasmonic substrate and analyte. Subsequent PSI treatment at high voltage conditions further impacts the overall SERS responses, where the signal sensitivity and homogeneity significantly increase throughout the entire substrate, suggesting the ready migration of adsorbed analytes regardless of their interfacial attractive forces. The PSI-induced notable SERS enhancements are presumably associated with creating unique conditions for local aggregation of the AuNPs to induce effective plasmonic couplings and hot spots (i.e., electromagnetic effect) and for repositioning analytes in close proximity to a plasmonic surface to increase polarizability (i.e., chemical effect). The optimized sampling and PSI conditions are also applicable to multi-analyte analysis by SERS and MS, with greatly enhanced detection capability and signal uniformity. [ABSTRACT FROM AUTHOR]

Submerged entry nozzle (SEN) clogging is investigated with an emphasis on the interfacial reaction between the nozzle refractory and the liquid steel. Within the context of carbothermically produced CO(g) being the main cause of the early stage SEN clogging, various SEN refractory materials are assessed in view of their impact on the initial clog deposit formation. A series of high‐temperature experiments are carried out to observe the interfacial reaction between the SEN refractory materials and the liquid steel: three oxide‐based and one oxide‐less refractory materials are employed. Ti‐free and Ti‐added ultra‐low C steel are reacted with these refractory materials. The reactivity of the refractories is assessed by 1) the morphology, composition, and thickness of the initial clog deposit and 2) the evolution of steel compositions. Decreasing SiO2 content in "oxide‐based" refractory is recommended. The "oxide‐less" refractory composed of AlON–BN–AlN is shown to be promising to suppress the early stage of SEN clogging. The present results would provide directions for designing the SEN refractory constitution to suppress the SEN clogging. [ABSTRACT FROM AUTHOR]

Urban green spaces contribute to improving people's physical and mental health by reducing levels of stress and anxiety. Marginalized communities in the USA experience poor health outcome in part because of health disparities related to social and structural determinants of health. The purpose of this study is to assess the prospective role of Kellogg Park, a newly built community park in a marginalized community in California, in enhancing residents' physical and mental health. The researchers collected the data by conducting an in-person survey, which covered questions related to environmental and safety perceptions, overall satisfaction, changes in physical activity changes and mental health with respondents' pre- and post-occupancy experiences. For analyzing data, bivariate analyses using a t-test and a correlation analysis were conducted to examine if there was a relationship between the overall satisfaction and visiting experience. The results indicated an increased positive environmental perception. Besides, respondents reported positively to questions of safety and their overall satisfaction. This research yielded positive results, indicating an improvement in the respondents' physical activity changes and mental health after the construction of the park. The results will advocate for and assist planners, designers, and policy-makers in prioritizing green spaces in marginalized communities. [ABSTRACT FROM AUTHOR]
