標題: Breaking the waves? Current prospects for gender equality in the maritime industry: the example of Taiwan 作者: Wu, Pei-Chi; Wang, Kuan-Jan; Liou, Chian; Lee, Kimberly Hsiu-Chin; Guo, Jiunn-Liang 摘要: Taiwanese maritime academies began admitting female students to study navigation and marine engineering in 1993. However, women seafarers currently account for only 3.41% of Taiwan's active seafarers, and this proportion has been decreasing since 2021. Given that gender equality is a fundamental human right, and in response to the International Maritime Organization's 1988 call to promote women's participation in sea-going roles, this study aims to broaden the seafaring paths available to Taiwanese women. Notably, the authors primarily collected research data through the first-ever 2024 Women Seafarers Forum held in Taiwan. This was supplemented by in-depth interviews and focus groups with former and current women seafarers, as well as female navigation and marine engineering students and cadets. Additionally, the study utilized the Immersion-Crystallization method, an ideal analytical approach in qualitative research, for data analysis. The findings are presented thematically, following a chronological timeline: the emergence of gender equality awareness, token women seafarers on cargo ships, stormy seas on the route, and moving towards a diverse, equitable, and inclusive seafaring profession. Through the final discussion, the authors hope this study will help Taiwan's seafaring workplaces move closer to achieving genuine gender equality.

標題: Electrically-Driven 2D Semiconductor Microcavity Laser 作者: Chen, Zheng-Zhe; Lin, Hsiang-Ting; Chang, Chiao-Yun; Adil, Muhammad; Tsai, Po-Cheng; Kao, Tsung Sheng; Chen, Chi; Lin, Shih-Yen; Shih, Min-Hsiung 摘要: 2D monolayered transition-metal dichalcogenides (TMDCs) are promising materials for realizing ultracompact, low-threshold semiconductor lasers. And the development of the electrical-driven TMDC devices is crucial for enhancing the integration potential of practical optoelectronic systems. However, at the current stage, the electrically-driven 2-D TMDC laser has never been realized. Herein, the first electrically-driven 2-D TMDC microcavity laser have been developed. In this device, an alternating current (AC) generates electroluminescence lasing in suspended monolayered WSe2 integrated on a microdisk cavity. The input-output curve, bandwidth narrowing, and second-order coherence is analyzed to confirm the lasing characteristics at room temperature. The realization of the room-temperature AC-driven 2-D TMDC laser establishes a new area of research on electrically pumped compact lasers and is likely to assist with the implementation of diverse TMDC-based practical photonic devices in the future.

標題: Student's t Kernel-Based Maximum Correntropy Criterion Extended Kalman Filter for GPS Navigation 作者: Jwo, Dah-Jing; Chang, Yi; Hsu, Yun-Han; Biswal, Amita 摘要: Global Navigation Satellite System (GNSS) receivers may produce measurement outliers in real-world applications owing to various circumstances, including poor signal quality, multipath effects, data loss, satellite signal loss, or electromagnetic interference. This can lead to a noise distribution that is non-Gaussian heavy-tailed, affecting the effectiveness of satellite navigation filters. This paper presents a robust Extended Kalman Filter (EKF) based on the Maximum Correntropy Criterion with a Student's t kernel (STMCCEKF) for GPS navigation under non-Gaussian noise. Unlike traditional EKF and Gaussian-kernel MCCEKF, the proposed method enhances robustness by leveraging the heavy-tailed Student's t kernel, which effectively suppresses outliers and dynamic observation noise. A fixed-point iterative algorithm is used for state update, and a new posterior error covariance expression is derived. The simulation results demonstrate that STMCCEKF outperforms conventional filters in positioning accuracy and robustness, particularly in environments with impulsive noise and multipath interference. The Student's t-distribution kernel efficiently mitigates heavy-tailed non-Gaussian noise, while it adaptively adjusts process and measurement noise covariances, leading to improved estimation performance. A detailed explanation of several key concepts along with practical examples are discussed to aid in understanding and applying the Global Positioning System (GPS) navigation filter. By integrating cutting-edge reinforcement learning with robust statistical approaches, this work advances adaptive signal processing and estimation, offering a significant contribution to the field.
