The Bˉs0→J/ψπ0η\bar B_s^0 \to J/\psi \pi^0 \eta decay and the a0(980)−f0(980)a_0(980)-f_0(980) mixing

We study the $\bar B_s^0 \to J/\psi f_0(980)$ and $\bar B_s^0 \to J/\psi a_0(980)$ reactions, and pay attention to the different sources of isospin violation and mixing of $f_0(980)$ and $a_0(980)$ resonances where these resonances are dynamically generated from meson-meson interaction. We find that the main reason of isospin violation is the isospin breaking in the meson-meson transition $T$ matrices, and the other source is that the loops involving kaons in the production mechanism provide a source of isospin violation because they do not cancel by the different mass of the charged and neutral kaons. We obtain a branching ratio for $a_0(980)$ production of the order of $5 \times 10^{-6}$. Future experiments can address this problem and the production rate and shape of the $\pi^0 \eta$ mass distribution will definitely help to better understand the nature of scalar resonances.Comment: 12 pages, 4 figure

J/ψJ/\psi decays into ω(ϕ)f1(1285)\omega (\phi) f_1(1285) and \omega (\phi) \,''f_1(1420)''

We perform a theoretical study of the $J/\psi \to \omega (\phi) K^* \bar{K} + c.c. \to \omega (\phi) K^0 \pi^+ K^-$ reactions with the assumption that the $f_1(1285)$ is dynamically generated from a single channel $K^* \bar{K} + c.c$ interaction in the chiral unitary approach. Two peaks in the $K^0 \pi^+ K^-$ invariant mass distribution are observed, one clear peak locates at the $f_1(1285)$ nominal mass, the other peak locates at around $1420\; \rm MeV$ with about $70 \;\rm MeV$ width. We conclude that the former peak is associated with the $f_1(1285)$ and the latter peak is not a genuine resonance but a manifestation of the kinematic effect in the higher energy region caused by the $K^* \bar{K} + c.c.$ decay mode of the $f_1(1285)$.Comment: 17 pages, 5 figures

Label Mask AutoEncoder(L-MAE): A Pure Transformer Method to Augment Semantic Segmentation Datasets

Semantic segmentation models based on the conventional neural network can achieve remarkable performance in such tasks, while the dataset is crucial to the training model process. Significant progress in expanding datasets has been made in semi-supervised semantic segmentation recently. However, completing the pixel-level information remains challenging due to possible missing in a label. Inspired by Mask AutoEncoder, we present a simple yet effective Pixel-Level completion method, Label Mask AutoEncoder(L-MAE), that fully uses the existing information in the label to predict results. The proposed model adopts the fusion strategy that stacks the label and the corresponding image, namely Fuse Map. Moreover, since some of the image information is lost when masking the Fuse Map, direct reconstruction may lead to poor performance. Our proposed Image Patch Supplement algorithm can supplement the missing information, as the experiment shows, an average of 4.1% mIoU can be improved. The Pascal VOC2012 dataset (224 crop size, 20 classes) and the Cityscape dataset (448 crop size, 19 classes) are used in the comparative experiments. With the Mask Ratio setting to 50%, in terms of the prediction region, the proposed model achieves 91.0% and 86.4% of mIoU on Pascal VOC 2012 and Cityscape, respectively, outperforming other current supervised semantic segmentation models.

Implementing universal nonadiabatic holonomic quantum gates with transmons

Geometric phases are well known to be noise-resilient in quantum evolutions/operations. Holonomic quantum gates provide us with a robust way towards universal quantum computation, as these quantum gates are actually induced by nonabelian geometric phases. Here we propose and elaborate how to efficiently implement universal nonadiabatic holonomic quantum gates on simpler superconducting circuits, with a single transmon serving as a qubit. In our proposal, an arbitrary single-qubit holonomic gate can be realized in a single-loop scenario, by varying the amplitudes and phase difference of two microwave fields resonantly coupled to a transmon, while nontrivial two-qubit holonomic gates may be generated with a transmission-line resonator being simultaneously coupled to the two target transmons in an effective resonant way. Moreover, our scenario may readily be scaled up to a two-dimensional lattice configuration, which is able to support large scalable quantum computation, paving the way for practically implementing universal nonadiabatic holonomic quantum computation with superconducting circuits.Comment: v3 Appendix added, v4 published version, v5 published version with correction

Xiaoyaosan Decoction, a Traditional Chinese Medicine, Inhibits Oxidative-Stress-Induced Hippocampus Neuron Apoptosis In Vitro

Xiaoyaosan (XYS) decoction is a famous prescription for the treatment of mental disorders in China. In this experiment, we explored the way in which XYS decoction-reverse hippocampus neuron apoptosis in vitro. We used XYS decoction-containing serum to treat oxidative-stress-induced hippocampus neuron apoptosis and used immunofluorescence to determine the concentration of free calcium, mitochondrial membrane potential, and apoptotic rate of neuron. Results showed that 3-hour oxidative stress decrease mitochondrial membrane potential, increase the concentration of free calcium and apoptotic rate of neuron via triggering pathological changes of nucleus such as karyorrhexis, karyopyknosis. Low, medium, high dose of XYS-decoction-containing serum could reverse these phenomenon, and the effect of low-dose XYS-decoction-containing serum was significant in improving mitochondrial membrane potential and apoptotic rate of neuron. These findings suggest that XYS decoction may be helpful in reducing oxidative-stress-induced hippocampus neuron apoptosis

Development and evaluation of a Traditional Chinese Medicine syndrome questionnaire for measuring sub-optimal health status in China

AbstractObjectiveSub-optimal health status (SHS), in which a person's mind and body exists in a low-quality state of being between disease and health, has become a public health problem that cannot be ignored in China. SHS measurement presents a challenge to the academic fields. We developed and evaluated a questionnaire from the perspective of traditional Chinese medicine (TCM) that embodies the features of TCM syndrome diagnosis for measuring SHS in China.MethodsThe construction of the theoretical framework of the questionnaire was based on a literature review, an expert questionnaire survey and group interviews. The subscales and questionnaire items were screened through a pilot study using statistical means and qualitative analysis. Reliability tests that were used included test-retest reliability, Cronbach's α coefficient, split-half reliability; validity tests included content validity, criterion validity, discrimination validity and construct validity.ResultsThe final questionnaire, the SHSQ-50, included 50 five-class quantifiable items that encompassed nine subscales: liver stagnation syndrome, liver-Qi deficiency syndrome, spleen-Qi deficiency syndrome, liver-fire syndrome, heart-fire syndrome, stomach-fire syndrome, heart-Qi deficiency syndrome, lung-Qi deficiency syndrome and dampness syndrome. Questionnaires were completed by 268 of the 288 SHS subjects (93.0%) and by 86 of the 94 healthy subjects (91.5%). The Cronbach α coefficients, split-half coefficients and stability coefficients ranged from 0.70 to 0.95, 0.67 to 0.87 and 0.88 to 0.98, respectively, for the overall scores and subscales. The Wilcoxon rank test showed statistically significant differences in the subscales and overall scores between the SHS group and the healthy group (P<0.01). Twelve factors with an eigenvalue greater than one were extracted by factor analysis and merged into nine factors, for which the cumulative contribution rate was 63.63%. The nine factors were corresponded to the overall structure of the questionnaire.ConclusionThe SHSQ-50 is a reliable and valid instrument for measuring TCM syndrome diagnosis of SHS in China
