A study of readers’ motivations and behavior with motivational books in Taiwan
This poster reports on the preliminary findings from a survey on Taiwan readers’ reading motivations and behavior with motivational books. The sample is composed of 435 avid adult readers. The poster will focus on the reading motivation for four major subgenres under motivational books as well as the age-related differences in information sharing and medium/access methods for motivational reading
Aorta Fluorescence Imaging by Using Confocal Microscopy
The activated leukocyte attacked the vascular endothelium and the associated increase in VEcadherin number was observed in experiments. The confocal microscopic system with a prism-based wavelength filter was used for multiwavelength fluorescence measurement. Multiwavelength fluorescence imaging based on the VEcadherin within the aorta segment of a rat was achieved. The confocal microscopic system capable of fluorescence detection of cardiovascular tissue is a useful tool for measuring the biological properties in clinical applications
Hydrothermal–galvanic couple synthesis of directionally oriented BaTiO3 thin films on TiN-coated substrates
AbstractBaTiO3 films were synthesized on TiN-coated Si substrate below 100°C by a hydrothermal–galvanic couple technique in barium contained alkaline solutions. X-ray diffraction and electron backscatter diffraction results show that the BaTiO3 thin films were directionally oriented grown on the TiN/Si substrates, i.e., (111) BaTiO3 over (111) TiN. The surface morphologies revealed that BaTiO3 nucleated and grew over the TiN surface with a single layer. From kinetic analyses, the growth rates of BaTiO3 films prepared by the hydrothermal–galvanic couple technique were faster than a hydrothermal method. The galvanic effects were confirmed by investigating the induced currents and energies. The galvanic currents were generated and controlled by both the dissolution of TiN and the formation of BaTiO3. The output electric energies increased rapidly with the reaction time and leveled off at the full coverage of BaTiO3
Bis[2-(2H-benzotriazol-2-yl)-4-methylphenolato]palladium(II)
In the title complex, [Pd(C13H10N3O)2], the PdII atom is tetracoordinated by two N atoms and two O atoms from two bidentate 2-(2H-benzotriazol-2-yl)-4-methylphenolate ligands, forming a square-planar environment. The asymmetric unit contains one half molecule in which the Pd atom lies on a centre of symmetry
Fusion of Diffusion Weighted MRI and Clinical Data for Predicting Functional Outcome after Acute Ischemic Stroke with Deep Contrastive Learning
Stroke is a common disabling neurological condition that affects about
one-quarter of the adult population over age 25; more than half of patients
still have poor outcomes, such as permanent functional dependence or even
death, after the onset of acute stroke. The aim of this study is to investigate
the efficacy of diffusion-weighted MRI modalities combining with structured
health profile on predicting the functional outcome to facilitate early
intervention. A deep fusion learning network is proposed with two-stage
training: the first stage focuses on cross-modality representation learning and
the second stage on classification. Supervised contrastive learning is
exploited to learn discriminative features that separate the two classes of
patients from embeddings of individual modalities and from the fused multimodal
embedding. The network takes as the input DWI and ADC images, and structured
health profile data. The outcome is the prediction of the patient needing
long-term care at 3 months after the onset of stroke. Trained and evaluated
with a dataset of 3297 patients, our proposed fusion model achieves 0.87, 0.80
and 80.45% for AUC, F1-score and accuracy, respectively, outperforming existing
models that consolidate both imaging and structured data in the medical domain.
If trained with comprehensive clinical variables, including NIHSS and
comorbidities, the gain from images on making accurate prediction is not
considered substantial, but significant. However, diffusion-weighted MRI can
replace NIHSS to achieve comparable level of accuracy combining with other
readily available clinical variables for better generalization.Comment: 12 pages, 5 figures, 5 table
