Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT
Astronomische Nachrichten, EarlyView.ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Deep Underground Science and Engineering, EarlyView.This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

EcoEnergy, EarlyView.Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

理论与实习相结合的教学模式在留学生心电图诊断学教学中的实践与探讨
Zhongguo shiyan zhenduanxue, 2018 心电图诊断学是临床医学生的必修课,是走向临床必须掌握的临床技能,心电图诊断学虽然只是一门小学科,但却是医学生的基础学科,而且由于理论课教学内容抽象难懂,心电图教学一直是教学难点之一,带教老师们也在一直尝试多种教学模式,包括尝试CBS、PBL、LBL相结合[1,2]及TBL与LBL相结合[3]等多种教学方式,比较新型教学方式与传统教学方法的效果[4]。我们心电图诊断学教学组也在医学本科生、研究生、留学生等不同生源的心电图诊断学教学中不断地摸索、尝试各种改革,以期达到满意的教学效果 ...

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.

A study on application of cases teaching in teaching of "Nursing Psychology"
Huli yanjiu, 2005 [目的 ]了解案例教学的效果。 [方法 ]对两个班次 2 5 7名学生实施案例教学 ,并用效果评价问卷调查案例教学的效果。 [结果 ]案例教学以其形象、模拟真实、理论联系实际和教学互动等特点而取得显著的教学成效 ,但也存在不能涵盖护理心理学的所有内容和花费时间较长等不足。 [结论 ]案例教学有其优势 ,但不是所有护理心理学的授课内容都能用案例教学 ,如果案例教学与其他教学法联合应用 ,将取得最佳教学成效。
