Published: March 2023

With the rapid development of science and technology, it is of great significance to study the influence of prince on sleeping time to explore the knowledge value of sleeping beauty. In this work, we use the data of American Physical Society to identify sleeping beauties according to B-index, and use logistic model and propensity score matching model to analyze the data. Then, we explore the impact of prince on the sleeping time of sleeping beauty. The results show that the prince has a significant inhibitory effect on the sleeping time of sleeping beauty, and the sleeping time of sleeping beauty cited by prince is shorter. The citation behavior of prince has the feature of self-selection. Using propensity score matching method can effectively overcome the problem of sample selection bias and obtain more reliable estimation results.
Emissivity Influence on Thermocouple Correction
Authors: Cai Mengyin , Huang Qinghuang , Yue Lingling , Wang Peiyong 
Published: March 2023

The reading of a thermocouple is not equal to the gas temperature because of the complicated heat transfer process among the thermocouple, the gas, and the environment. So the corrections for thermocouple measurements are necessary to obtain the real gas temperature. The current correction methods using multiple thermocouples assume that the thermocouples have the same surface emissivity. However, the emissivity of a thermocouple depends on its surface condition, and the emissivity of the thermocouples normally are different. CFD simulations are carried out to study the influence of emissivity difference on the correction accuracy. For the extrapolation method, the correction accuracy could be improved or weakened depending on the emissivity variation of the thermocouples. For the equation methods by De, the correction accuracy is poor for the low speed flow and good for the high speed flow. However, the correction accuracy for the high speed flow is weakened if the emissivity of the thermocouples have large difference. For the equation method by Brohez, the overall correction accuracy is good but the accuracy degrades greatly with the large emissivity difference of the thermocouples.
Effect of Melt Holding Time on the As-cast Microstructure and Hardness of Aluminum Alloy 2618
Authors: Chen Shanshan , Chai Zhizhang , Huang Zicheng 
Published: March 2023

The effects of the melt holding time on the type, quantity and morphological distribution of aluminum alloy 2618 were investigated by means of OM, XRD and SEM. And the influence of the melt holding time on the hardness of alloy was explored. The results show that the heredity of the microstructure of the master alloy is not completely eliminated when the melt holding time is less than 10 min at 740 ℃. And it will make Al9FeNi phase coarse needle-like, and segregate with Al7Cu2Fe phase at the grain boundary or inside the grain. Properly prolonging the melt holding time can change the shape of Al9FeNi phase from coarse needle-like to fine needle-like and make the distribution of Al9FeNi phase and Al7Cu2Fe phase more uniform. Aluminum alloy 2618 was melted at 740 ℃ for 30 min and then poured into graphite molds at room temperature, which can make Al9FeNi phase fine and uniformly distributed in the matrix. With the extension of the melt holding time, the size of the nonequilibrium crystalline phase is basically unchanged, but the grain size will be slightly coarsened. The hardness of the alloy showed a trend of first increasing and then decreasing with the prolongation of the melt holing time within 10~60min, and when the melt was held for 30min, the hardness of the alloy reached the maximum HRB value of Rockwell hardness within the range of this test. The maximum value is 48.62HRB, and the hardness distribution of the alloy is relatively uniform. Therefore, it is beneficial to refine the precipitated phase, reduce the macro segregation, and refine the grain and improve the hardness of the alloy, while alloy 2618 was poured into the graphite casting at room temperature with melting at 740℃ and held for 30min.
The bedrock river profile fitting and the indicative significance: a case study in Gyirong watershed of the Middle Himalaya
Authors: Chen Lu , Ran Qinghong 
Published: March 2023

Area-slope (AS) Model focuses on quantitative study of bedrock river which has been widely used in the longitudinal profile simulation of bedrock and alluvial rivers, but many applications have failed to carefully consider the mechanism, fitting effect and applicability, resulting in unsatisfactory simulation results. In order to verify the channel profile analysis capability, the study analyzes the oretical basis of AS model and applies to the river channel fitting and knickpoint identification in the Gyirong Watershed in the middle Himalayan Orogen. The results show that, for rivers with different equilibrium status, the fitting curves have different splattering patterns. More than 80% knckpoints locate on the elevation between 4000 –5050 m where coincided with Tibetan Himalayan Unit. Although climate affects the spatial distribution of knickpoints, the structure of Gyirong watershed have developed before modern climate pattern.
Gray and White Matters Segmentation in Brain CT Images using Multi-Task Learning from Paired CT and MR Images
Authors: Han Taohai , Wang Hongkai 
Published: March 2023

Computer tomography (CT) has been routinely used for decades in clinical neuroimaging. Compared to Magnetic resonance imaging (MR), CT is more readily available and more cost-effective, but the soft tissue contrast is much lower. In brain CT images, the unclear soft-tissue boundaries and the high noise level hamper accurate segmentation of the gray and white matter, leaving obstacles for the subsequent geometrical quantification of brain structures. To address this challenge, this paper specifically acquires same-patient CT and MR image pairs and proposes a multi-task learning model for simultaneous tissue segmentation and modality transfer. We aim to use the modality transfer task to learn corresponding MR and CT features which assists the segmentation task to achieve more accurate results than single modality learning. Moreover, we add a Shannon entropy loss function to the training loss to further combat the high noise influence and reduce the fragmentation problem of the segmentation results. Experimental results proved that our multi-task framework achieves more accurate segmentation than the single segmentation task, and the Shannon entropy loss results in much fewer broken brain regions than the state-of-the-art (SOTA) U-net method. Our study provides a useful tool for clinical neural CT image analysis.

Authors: Wang Ke 
Published: March 2023

Driven By the Low Carbon Policy, low-carbon road infrastructure construction is greatly concerned. The lack of standardized quantification of energy consumption and carbon emissions limits the universality of Low Carbon road construction practice. Based on the national road cost management software and China's life cycle core database, the standardized quantification method of energy consumption and carbon emissions is established. Empirical project data are used to check the Effectiveness of the method. The method is to screen out the design measure with better energy conservation and lower carbon emission.

Authors: BROUGHTON ALTA J. , CATANIA NICHOLAS , HOPPEY DAVID , ALLSOPP DAVID 
Published: March 2023

ABSTRACT
The majority of teacher preparation for culturally and linguistically diverse student populations has focused on the development of beliefs and attitudes of White general education teachers. This leaves much to be understood as to the development of belief systems of teachers with Latinx heritage and how they relate to their students with disabilities. This study applied theories of critical race theory and funds of knowledge to better understand how the cultural and linguistic backgrounds of our teacher candidates were key to fostering the development of their teacher identities. This resulted in the development of the Cultivating Critical Consciousness in Educators Framework (CCCE), a comprehensible framework for understanding the beliefs and practices essential for educators to practice critical consciousness. Findings demonstrate within group diversity of beliefs varying along a continuum of dysconscious to critical consciousness related to systemic racism, ableism, discrimination based on sexual orientation and/or gender expression, and sociolinguistic issues. Implications for teacher education practice and future research also are shared.
