Abstract

Light carries both longitudinal and transverse spin angular momentum. The spin can couple with its orbital counterpart via the Berry phase, known as the spin-orbit interaction (SOI) of light. The SOI of light discovered previously belongs to the longitudinal one, which relies on the Berry phase in momentum space, such as the optical Magnus effect and the spin Hall effect. Here, we show that transverse SOI, relying on the Berry phase in real space, is inherent in the Helmholtz equation when transverse spinning light propagates in curved paths. The transverse SOI lifts the degeneracy of dispersion relations of light for opposite transverse spin states, analogous to the Dresselhaus effect. Transverse SOI is ubiquitous in nanophotonic systems where transverse spin and optical path bending are inevitable. It can also explain anomalous effects like the dispersion relation of surface plasmon polariton on curved paths and the energy level of whispering gallery modes. Our results reveal the analogies of spin photonics and spintronics and offer a new degree of freedom for integrated photonics, spin photonics, and astrophysics.

Abstract

The sixth generation (6G) mobile communications have attracted substantial attention in the global research community of information and communication technologies (ICT). 6G systems are expected to support not only extended 5G usage scenarios, but also new usage scenarios, such as integrated sensing and communication (ISAC), integrated artificial intelligence (AI) and communication, and communication and ubiquitous connectivity. To realize this goal, channel characteristics must be comprehensively studied and properly exploited, so as to promote the design, standardization, and optimization of 6G systems. In this paper, we first summarize the requirements and challenges in 6G channel research. Our focus is on channels for five promising technologies enabling 6G, including terahertz (THz), extreme MIMO (E-MIMO), ISAC, reconfigurable intelligent surface (RIS), and space-air-ground integrated network (SAGIN). Then, a survey of the progress of the 6G channel research regarding the above five promising technologies is presented in terms of the latest measurement campaigns, new characteristics, modeling methods, and research prospects. Moreover, a tutorial on the 6G channel simulations is presented. We introduce the BUPTCMG- 6G, a 6G link-level channel simulator, developed based on the ITU/3GPP 3D geometry-based stochastic model (GBSM) methodology. The simulator supports the channel simulation of the aforementioned 6G potential technologies. To facilitate the use of the simulator, the tutorial encompasses the design framework, user guidelines, and application examples. This paper offers in-depth, hands-on insights into the best practices of channel measurements, modeling, and simulations for the evaluation of 6G technologies, the development of 6G standards, and the implementation and optimization of 6G systems., Comment: 41 pages,52 figures

13. Developing a Reading Strategic Competence Scale for Chinese Tertiary EFL Learners

Author

Zhou, Yanqiong, Lin, Jiaxin, and Yang, Zhuojun

Abstract

Despite the important role of strategies in language learning, they have not been afforded much attention in the development of language proficiency scales. This study, situated in a nationwide project of developing China's Standards of English language ability, presents in detail the development of a reading strategic competence scale for Chinese tertiary EFL learners, including determining the descriptive scheme, establishing the descriptor pool, constructing a preliminary scale by panel experts, and validating the calibration by Rasch Model scaling. According to the study, reading strategies are hierarchical in difficulty levels, and two levels can be set for Chinese tertiary EFL learners. A very clear progression is visible in the content of the final scale. Based on the findings, pedagogical implications for teachers and learners to use the scale are discussed.

Abstract

Background Methods Results Conclusions Plain Language Summary The surgical treatment of retroperitoneal sarcoma (RPS) is highly challenging because of its complex anatomy. In this study, the authors compared the surgical outcomes of patients with RPS who underwent surgical resection guided by three‐dimensional (3D) printing technology versus traditional imaging.This retrospective study included 251 patients who underwent RPS resection guided by 3D‐printing technology or traditional imaging from January 2019 to December 2022. The main outcome measures were operative time, intraoperative blood loss, postoperative complications, and hospital stay.In total, 251 patients were enrolled in the study: 46 received 3D‐printed navigation, and 205 underwent traditional surgical methods. Propensity score matching yielded 44 patients in the 3D group and 82 patients in the control group. The patients' demographics and tumor characteristics were comparable in the matched cohorts. The 3D group had significantly shorter operative time (median, 186.5 minutes [interquartile range (IQR), 130.0–251.3 minutes] vs. 210.0 minutes [IQR, 150.8–277.3 minutes]; p = .04), less intraoperative blood loss (median, 300.0 mL [IQR, 100.0–575.0 mL] vs. 375.0 mL [IQR, 200.0–925.0 mL]; p = .02), shorter postoperative hospital stays (median, 11.0 days [IQR, 9.0–13.0 days] vs. 14.0 days [IQR, 10.8–18.3 days]; p = .02), and lower incidence rate of overall postoperative complications than the control group (18.1% vs. 36.6%; p = .03). There were no differences with regard to the intraoperative blood transfusion rate, the R0/R1 resection rate, 30‐day mortality, or overall survival.Patients in the 3D group had favorable surgical outcomes compared with those in the control group. These results suggest that 3D‐printing technology might overcome challenges in RPS surgical treatment. The surgical treatment of retroperitoneal sarcoma (RPS) is highly challenging because of its complex anatomy. The purpose of this study was to investigate whether three‐dimensional (3D) printing technology offers advantages over traditional two‐dimensional imaging (such as computed tomography and magnetic resonance imaging) for guiding the surgical treatment of RPS. In a group of patients who had RPS, surgery guided by 3D‐printing technology was associated with better surgical outcomes, including shorter operative time, decreased blood loss, shorter hospital stays, and fewer postoperative complications. These findings suggested that 3D‐printing technology could help surgeons overcome challenges in the surgical treatment of RPS. 3D‐printing technology has important prospects in the surgical treatment of RPS.
