Music listening has been found to be effective in reducing stress levels with different participant samples. Relatively little evidence has been obtained from people with high neurotic tendency ...(HNT), whose dispositional psychological characteristics might dampen the effect of music listening. This study therefore tried to examine the immediate effect of music listening in reducing stressful feelings of participants with either high or low neurotic tendency.
Seventy-nine undergraduate participants who were identified as having either HNT or low neurotic tendency (LNT) accomplished a stressful task before listening to a comforting music piece. Negative affect (NA) scores and heart rate were measured at different phases.
Results in a within-subjects analysis showed that the stressor and music listening could significantly alter the stressful feeling of both participant groups. Although the percentage changes in heart rate were similar between the groups, the changes of NA score which were measured after either the stressful task or the music listening session were consistently lower in the HNT group than the LNT group.
The divergence revealed a loose connection between the subjective feelings and the bodily changes in the HNT group, which could be important for clinicians and practitioners to take into consideration in psychology when evaluating the stressful feelings for their clients with HNT.
Purpose
Euthyroid Graves’ ophthalmology (EGO) refers to the subgroup of thyroid eye disease patients with distinct clinical presentations. This study evaluated the ocular surface and meibomian gland ...changes in EGO patients.
Methods
A cross-sectional study was conducted at The Chinese University of Hong Kong including 34 EGO patients and 34 age-and sex- matched healthy controls. Outcome measures include anterior segment examination, keratographic and meibographic imaging.
Results
Between 34 EGO patients and 34 age and sex-matched healthy controls, EGO was associated with a higher ocular surface disease index (
P
< 0.01), higher severity of meibomian gland dropout (upper:
P
< 0.001, lower:
P
< 0.00001) and higher percentage of partial blinking (
P
= 0.0036). The worse affected eyes of the EGO patients were associated with corneal staining (
P
= 0.0019), eyelid telangiectasia (
P
= 0.0009), eyelid thickening (
P
= 0.0013), eyelid irregularity (
P
= 0.0054), meibomian gland plugging (
P
< 0.00001), expressibility (
P
< 0.00001), and meibum quality (
P
< 0.00001). When the two eyes of the same EGO patient were compared, the degree of meibomian gland dropout was higher among the worse affected eyes (upper:
P
< 0.00001, and lower:
P
< 0.00001). Tear meniscus height, lipid layer thickness, and noninvasive break-up time were comparable between the two eyes of EGO patients and also between EGO patients and healthy controls. TMH was positively correlated with the degree of exophthalmos (
r
= 0.383,
P
< 0.05).
Conclusion
EGO patients have more ocular surface complications and meibomian gland dropouts than healthy controls. Almost 60% of them had dry eye symptoms, but aqueous deficiency was not apparent. Further studies are warranted to clarify the mechanism of dry eye in EGO.

The pocket-sized ultrasound machine has emerged as an invaluable tool for quick assessment in emergency and general practice settings. It is suitable for instant and quick assessment in cardiac ...imaging. However, its applicability in the imaging of other body parts has yet to be established. In this pictorial review, we compared the performance of the pocketsized ultrasound machine against the standard ultrasound machine for its image quality in common abdominal pathology.
Coronary artery perforation is a rare but serious complication during percutaneous coronary intervention. Distal or small vessel perforation is usually treated by coil, fat, or microsphere ...embolization. We describe 5 cases of distal coronary perforation that were managed successfully by a novel technique that uses absorbable sutures. (Level of Difficulty: Advanced.)

A number of physical and chemical models have been built to describe secondary aerosols (SAs) in the atmosphere; however, direct experimental approaches to simultaneously characterizing the chemical ...structures and physical properties on the single-particle level are lacking. This lack obscures our understanding of SA formation mechanisms and impedes the development on the accurate prediction and control of air pollution. Here we obtained clear core–shell structural information about the aqueous aerosols employing low-voltage transmission electron microscopy–energy dispersive spectroscopy. The prevalent 10–20% surface tension reduction due to organic matter partitioning has been unveiled. Further analysis and modeling show that smaller SAs can yield greater surface tension reduction, while the pronounced surface tension reduction may enlarge the size of SAs by ≤50%. Our work paves the way for an unprecedented comprehensive single-particle study of the global atmospheric SA problem.

Objective To establish an automatic segmentation algorithm using convolution neural network, and to validate the consistency between the algorithm and manual segmentation. Methods One hundred ...andforty⁃six CT scans of intracerebral hemorrhage (ICH) were included from Chinese Intracranial Hemorrhage Image Database (CICHID). They were randomly divided into training set (n=90), testing set (n=26) and validation set(n=30). All CT scans were manual segmentation. Training set and testing set were used for algorithm training. The validation set was measured by four methods including manual segmentation, algorithm segmentation, accurate Tada formula and traditional Tada formula. The consistency test was performed. Results Compared with the Tada formula methods, the percentage error ofalgorithm values was the smallest 15.54 (8.41,23.18) %, and algorithm agreement with the manual reference was the strongest (correlation coefficient 0.983). Bland⁃Altman analysis showed that 93.33% of the data was within the 95% limits of agreement (95%LoA), and 95%LoA was narrow (⁃ 6.46-5.97 ml). No significant differences were found in size and shape (P > 0.05, for all). Conclusions The algorithm using convolutional neural network has a certain application prospect, but it needs still more validation in large sample research.

The paper provides a computational procedure for a type of robust regional pole assignment problem. It allows closed-loop poles to be settled at certain perturbation insensitive locations within some ...prespecified regions in the complex plane. The novelty of our approach lies in the versatility of the proposed algorithm which provides a rick set of constrained subregions applicable for the assignment of individual or subsets of closed-loop poles, in contrast to other conventional regional pole assignment methods. The algorithm is based on a gradient flow formulation on a differentiable potential function which provides a minimizing solution for the Frobenius condition number of the closed-loop eigenvector matrix. A numerical example is employed to illustrate the technique. The improvement on the eigenstructure robustness is compared with different kinds of constrained region.
