Preliminary Study on Learning Content Regarding Transitional Justice Education in High School History Textbooks
2018年教育部公布《十二年國民基本教育社會領域課程綱要》,在國家層級課程綱要,首次宣示轉型正義教學之必要,然而轉型正義教育包含哪些核心概念?教科書涵蓋哪些內容較能落實轉型正義的理念?有待釐清。本研究以戰後臺灣威權體制對人權造成的侵害為探討範疇,透過訪談先初步形塑轉型正義教育的項目及內涵,再透過德懷術建構「轉型正義教育學習內容」之「項目」(核心學習概念)及「條目」(提問要點)。最後本研究提出「理解歷史真相」、「探討追求正義的作為」、「反思和解與不再發生」三構面可探討的學習概念15項,及可引導教與學思考的28條提問,提供教材編撰及教學設計時參考。補正完畢TW

Inverse spectral problems for Sturm-Liouville operators with many frozen arguments
This study is devoted to the inverse spectral problems of the Sturm-Liouville operator with many frozen arguments. Under certain assumptions, the authors obtained the uniqueness theorems for recovering the operator from one spectrum. Finally, a numerical simulation of the inverse problem is given.補正完畢NL
A Low Power Sigma-Delta Modulator for Dual-Mode Wide-Band Receiver
This work presents a low power cascaded sigma-delta modulator for GSM and WCDMA applications. The proposed modulator has the characteristics of wide bandwidth for WCDMA applications and low distortion in the low frequency band for GSM applications. Low-distortion and interpolative techniques are used in this modulator to enhance the performance. The low-distortion technique has not only the swing-suppressing characteristic, but it can reduce the power consumption. Moreover, the resolution can be improved even under non-linearity effects. An experimental chip is implemented in the standard 0.18-μm 1P6M CMOS technology. The measurements indicate a dynamic range of 76/68 dB and a peak signal to noise plus distortion ratio of 70/61 dB for GSM/WCDMA applications. The core area is 1 × 1.4 mm2 and the power consumption is 10.5/28 mW for GSM/WCDMA at 1.8 V.補正完畢US
晶格結構滲透性數值分析
As the need for efficient heat extraction grows with decreasing extraction areas, enhancing heat transfer device performance is crucial. Porous structures in thermal devices like heat pipes and vapor chambers can significantly improve heat transfer. Permeability, vital in fluid dynamics, affects fluid flow in porous materials, such as lattice structures. This study uses numerical analysis to assess the permeability of lattice structures, created using nTopology and analyzed with ANSYS Fluent software. It focuses on Octet, Isotruss, and Diamond lattice geometries. The research considers lattice geometry, unit cell characteristics, flow conditions, and other factors to deeply understand these structures' behavior. Insights into how different parameters influence lattice behavior and permeability are gained. The study also examines the impact of beam thickness and porosity on lattice performance. By varying and comparing these aspects, the study seeks to develop a more thorough framework for permeability research, contributing to advancements in lattice structure design and engineering applications.補正完畢TW
Correlations for an anisotropic polarized stochastic gravitational wave background in pulsar timing arrays
The recent compelling observation of the nanohertz stochastic gravitational wave background has brought to light a new galactic arena to test gravity. In this paper, we derive a formula for the most general expression of the stochastic gravitational wave background correlation that could be tested with pulsar timing and future square kilometer arrays. Our expressions extend the harmonic space analysis, also often referred to as the power spectrum approach, to predict the correlation signatures of an anisotropic polarized stochastic gravitational wave background with subluminal tensor, vector, and scalar gravitational degrees of freedom. We present the first few nontrivial anisotropy and polarization signatures in the correlation and discuss their dependence on the gravitational wave speed and pulsar distances. Our results set up tests that could potentially be used to rigorously examine the isotropy of the stochastic gravitational wave background and strengthen the existing constraints on possible non-Einsteinian polarizations in the nanohertz gravitational wave regime.補正完畢GB
Synthesis of quinoxalines and assessment of their inhibitory effects against human non-small-cell lung cancer cells
Twenty-six quinoxalin derivatives were synthesized to assess their biological activities against human non-small-cell lung cancer cells (A549 cells). Compound 4b (IC50 = 11.98 ± 2.59 μM) and compound 4m (IC50 = 9.32 ± 1.56 μM) possess anticancer activity comparable to 5-fluorouracil (clinical anticancer drug) (IC50 = 4.89 ± 0.20 μM). Western blot tests further confirmed that compound 4m effectively induced apoptosis of A549 cells through mitochondrial- and caspase-3-dependent pathways. The introduction of bromo groups instead of nitro groups into the quinoxaline skeleton has been shown to provide better inhibition against lung cancer cells in this article. This modification in the molecular structure could enhance the biological activity and effectiveness of quinoxaline derivatives in the design and synthesis of anticancer drugs, making bromo-substituted quinoxalines a promising avenue for further research and development in anticancer therapeutics.補正完畢GB
