Tris[2-ethoxy-6-(methyliminomethyl)phenolato-κ2 N,O 1]cobalt(III) monohydrate
In the title compound, [Co(C10H12NO2)3]·H2O, the CoIII ion is coordinated by three O atoms and three N atoms from three bidentate 2-ethoxy-6-(methyliminomethyl)phenolate ligands in a slightly distorted octahedral environment. The water molecule connects two ligands by O—H⋯O hydrogen bonds. One terminal methyl group is disordered over two positions, with site-occupancy factors of 0.412 (15) and 0.588 (15)
Perceptual Image Compression with Cooperative Cross-Modal Side Information
The explosion of data has resulted in more and more associated text being
transmitted along with images. Inspired by from distributed source coding, many
works utilize image side information to enhance image compression. However,
existing methods generally do not consider using text as side information to
enhance perceptual compression of images, even though the benefits of
multimodal synergy have been widely demonstrated in research. This begs the
following question: How can we effectively transfer text-level semantic
dependencies to help image compression, which is only available to the decoder?
In this work, we propose a novel deep image compression method with text-guided
side information to achieve a better rate-perception-distortion tradeoff.
Specifically, we employ the CLIP text encoder and an effective Semantic-Spatial
Aware block to fuse the text and image features. This is done by predicting a
semantic mask to guide the learned text-adaptive affine transformation at the
pixel level. Furthermore, we design a text-conditional generative adversarial
networks to improve the perceptual quality of reconstructed images. Extensive
experiments involving four datasets and ten image quality assessment metrics
demonstrate that the proposed approach achieves superior results in terms of
rate-perception trade-off and semantic distortion
Ultrasound cavitation induced nucleation in metal solidification: an analytical model and validation by real-time experiments
Microstructural refinement of metallic alloys via ultrasonic melt processing (USMP) is an environmentally friendly and promising method. However, so far there has been no report in open literature on how to predict the solidified microstructures and grain size based on the ultrasound processing parameters.In this paper, an analytical model is developed to calculate the cavitation enhanced undercooling and the USMP refined solidification microstructure and grain size for Al-Cu alloys. Ultrafast synchrotron X-ray imaging and tomography techniques were used to collect the real-time experimental data for validating the model and the calculated results. The comparison between modeling and experiments reveal that there exists an effective ultrasound input power intensity for maximizing the grain refinement effects for the Al-Cu alloys, which is in the range of 20-45 MW/m2. In addition, a monotonous increase in temperature during USMP has negative effect on producing new nuclei, deteriorating the benefit of microstructure refinement due to the application of ultrasound
Clinical research on liver reserve function by 13C-phenylalanine breath test in aged patients with chronic liver diseases
<p>Abstract</p> <p>Background</p> <p>The objective of this study was to investigate whether the <sup>13</sup>C-phenylalanine breath test could be useful for the evaluation of hepatic function in elderly volunteers and patients with chronic hepatitis B and liver cirrhosis.</p> <p>Methods</p> <p>L-[1-<sup>13</sup>C] phenylalanine was administered orally at a dose of 100 mg to 55 elderly patients with liver cirrhosis, 30 patients with chronic hepatitis B and 38 elderly healthy subjects. The breath test was performed at 8 different time points (0, 10, 20, 30, 45, 60, 90, 120 min) to obtain the values of Delta over baseline, percentage <sup>13</sup>CO<sub>2 </sub>exhalation rate and cumulative excretion (Cum). The relationships of the cumulative excretion with the <sup>13</sup>C-%dose/h and blood biochemical parameters were investigated.</p> <p>Results</p> <p>The <sup>13</sup>C-%dose/h at 20 min and 30 min combined with the cumulative excretion at 60 min and 120 min correlated with hepatic function tests, serum albumin, hemoglobin, platelet and Child-Pugh score. Prothrombin time, total and direct bilirubin were significantly increased, while serum albumin, hemoglobin and platelet, the cumulative excretion at 60 min and 120 min values decreased by degrees of intensity of the disease in Child-Pugh A, B, and C patients (P < 0.01).</p> <p>Conclusions</p> <p>The <sup>13</sup>C-phenylalanine breath test can be used as a non-invasive assay to evaluate hepatic function in elderly patients with liver cirrhosis. The <sup>13</sup>C-%dose/h at 20 min, at 30 min and cumulative excretion at 60 min may be the key value for determination at a single time-point. <sup>13</sup>C-phenylalanine breath test is safe and helpful in distinguishing different stages of hepatic dysfunction for elderly cirrhosis patients.</p

Contour error compensation based on feed rate adjustment
To improve the performance of computer numerical control (CNC) machining, especially for large-curvature trajectories, this paper presents a contour error compensation algorithm based on reference trajectory modification. In order to estimate the contour error accurately and efficiently, a contour error estimation model is established. The reference trajectory is modified on the basis of the estimated contour error and partitioned into different segments, which adopt different feed rates according to a corner detection algorithm. The effectiveness of this contour error compensation algorithm is verified by experiments on a CNC machine tool
