Production of the top-pions at the THERA collider based γp\gamma p collisions

In the framework of the topcolor-assisted technicolor (TC2) models, we study the production of the top-pions $\pi^{0}_{t}$, $\pi_{t}^{\pm}$ via the processes $ep\to\gamma c\to\pi^{0}_{t}c$ and $ep\to\gamma c\to\pi^{\pm}_{t}b$ mediated by the anomalous top coupling $tc\gamma$. We find that the production cross section of the process $ep\to\gamma c\to\pi^{0}_{t}c$ is very small. With reasonable values of the parameters in TC2 models, the production cross section of the process $ep\to\gamma c\to\pi^{\pm}_{t}b$ can reach $1.2pb$. The charged top-pions $\pi^{\pm}_{t}$ might be directly observed via this process at the THERA collider based $\gamma p$ collisions.Comment: 10 pages, 3 figure

Littlest Higgs model and associated ZH production at high energy e+e−e^{+}e^{-} collider

In the context of the littlest Higgs (LH) model, we consider the Higgs strahlung process $e^{+}e^{-}\to ZH$. We find that the correction effects on this process mainly come from the heavy photon $B'$. If we take the mixing angle parameter $c$ in the range of 0.75 - 1, the contributions of the heavy gauge boson $W_{3}'$ is larger than 6%. In most of the parameter space, the deviation of the total production cross section $\sigma^{tot}$ from its SM value is larger than 5%, which may be detected in the future high energy $e^{+}e^{-}$ collider (LC) experiments. The future LC experiments could test the LH model by measuring the cross section of the process $e^{+}e^{-}\to ZH$.Comment: 13 pages, 3 figure

A disease forecast and early warning system based on electronic health records

Conference Name:8th International Conference on Computer Science and Education, ICCSE 2013. Conference Address: Colombo, Sri lanka. Time:August 26, 2013 - August 28, 2013.Disease forecast and early warning have been always important but difficult tasks. Because of the drawbacks of traditional records, the electronic health records, which bring in the ICD-10, are used in our system. Input information are firstly de-duplicated to remove redundancy. After that, the system are used for disease early warning and forecast. The results show that the proposed system has great help for the health sector to prevent and control the diseases. ? 2013 IEEE

A machine learning based study on pedestrian movement dynamics under emergency evacuation

Knowledge of evacuees' movement dynamics is crucial to building safety design and evacuation management. Although it is recognized that stepwise movement is the fundamental element to construct the whole evacuation process, movement pattern and its influencing factors are still not well understood. In this study, we explored the potential of adopting machine learning methods to study evacuees' stepwise movement1 dynamics based on two videos of quasi-emergency evacuation experiments. The movement patterns were categorized through Two-step Cluster Analysis and principal influencing factors were identified through Principal Component Analysis. The relationship between the movement patterns and the principal components were investigated using different modeling methods: traditional method (Multinomial Logit Model, MLM) and machine learning methods (Decision Tree, Support Vector Machine, K-Nearest Neighbor, and Artificial Neural Network). Results from two experimental videos showed reasonable consistency and the main findings are: (1) Distance to the target exit has the most pronounced effect on a single evacuee's stepwise movement pattern. (2) Surrounding evacuees' actions also have significant and complex influence on a single evacuee's stepwise movement pattern. (3) MLM showed comparable prediction accuracy with machine learning methods when the scenario is simple. The superiority of machine learning became apparent when the scenario was more complex, with a maximum enhancement of 13.25% in prediction accuracy. Each machine learning method demonstrated distinct features and advantages in different aspects.Nanyang Technological UniversityAccepted versionThis study is conducted under the financial support from NTU (Nanyang Technological University) Research Scholarship.

A novel TSC2 c.4511 T > C missense variant associated with tuberous sclerosis complex

Background Tuberous sclerosis complex (TSC) is an autosomal-dominant hereditary disease characterized by hamartomas of multiple organ systems, including the brain, skin, heart, kidney and lung. Genetically, TSC is caused by pathogenic variants in the TSC1 or TSC2 gene. Case presentation We reported a sporadic case of a 32-year-old Han Chinese male diagnosed with TSC, whose spouse had a history of two spontaneous miscarriages and an induced abortion of a 30-week fetus identified with cardiac rhabdomyoma by ultrasound. A novel heterozygous missense variant in the TSC2 gene (Exon35:c.4511?T?>?C:p.L1504P) was identified in the male patient and the aborted fetus by next-generation sequencing, but not in his wife or both his parents. According to the ACMG Conclusion The novel TSC2 :c.4511?T?>?C variant identified was highly likely associated with TSC and could potentially lead to adverse reproductive outcomes. IVF-ET and pre-implantation genetic diagnosis for TSC are recommended for this patient in the future to prevent fetal TSC

FBG-Based Sensitivity Structure Based on Flexure Hinge and Its Application for Pipeline Pressure Detection

With the widespread application of pipelines in engineering, more and more accidents occur because of pipeline leakage. Therefore, it is particularly important to continuously monitor the pipeline pressure. In this study, a non-intrusive and high-sensitivity structure based on FBG (Fiber Bragg grating) sensor is proposed. Firstly, the basic sensing theory of FBG and the state of a pipeline wall under inner pressure are analyzed. Then, structural sensitivity is deduced based on the flexure hinge and mechanical lever. Subsequently, finite element simulation for the whole sensitization structure is carried out, and optimal parameters are determined to obtain the maximum sensitivity. Finally, laboratory experiments are conducted to verify the function of the designed sensitivity structure. The experimental results show a good agreement with the simulation results. In the experiment, it can be found that the designed structure has a strain sensitivity of 9.59 pm/με, which is 11.51 times the pipeline surface strain. Besides, the structure is convenient to operate and has a good applied prospect for the engineering practice

The development of reading comprehension ability of Chinese Heritage Language (CHL) learners in Indonesia

Abstract This study investigates the evolution of reading comprehension abilities in Indonesian learners of the Chinese Heritage Language (CHL), by comparing their scores on the Chinese Proficiency Test, a test specifically designed for CHL learners. A total of 275 candidates, divided into early adolescent (M age = 13.56), late adolescent (M age = 15.78), and adult (M age = 22.83) groups, were evaluated on four dimensions of reading comprehension: orthographic knowledge, vocabulary knowledge, syntactic awareness, and discourse comprehension. A detailed cross-sectional and longitudinal analysis of these four dimensions was conducted across the three groups. The results indicate that horizontally, the order of the four dimensions is orthographic knowledge > vocabulary knowledge > syntactic awareness > discourse comprehension, with significant differences observed in all dimensions. During adolescence, orthographic knowledge is significantly higher than vocabulary knowledge, while in adulthood, vocabulary knowledge is significantly higher than syntactic awareness, and syntactic awareness is significantly higher than discourse comprehension. Longitudinally, reading comprehension abilities appear to stall across adolescence in three dimensions (vocabulary knowledge, syntactic awareness, and discourse comprehension), with a decline in one dimension (orthographic knowledge) occurring in late adolescence. However, the adult group shows improvement in all four dimensions compared to the late adolescence group. Considering both longitudinal and cross-sectional results, the developmental order of reading skills in Indonesian CHL learners is orthographic knowledge, vocabulary knowledge, syntactic awareness, and discourse comprehension. The main developmental peak for orthographic knowledge to vocabulary knowledge occurs in adolescence, while the major developmental peak for vocabulary knowledge to syntactic awareness and for syntactic awareness to discourse comprehension occurs in adulthood. The results suggest that reading comprehension improves significantly upon reaching adulthood in Indonesian. By understanding the trajectory of reading comprehension abilities in Indonesian CHL learners, this study can provide effective suggestions for Indonesian CHL learners and educators, and may also serve as a reference for other heritage languages
