Abstract

Objective: To find the most suitable cooling rate to meet people's requirements for apple storage quality at low temperature. Methods: The changes of apple tissue and cell structure were observed by low-temperature cold table equipment, and the changes of freezing temperature before and after cooling were compared and analyzed. Meanwhile, the changing trends of area, roundness, circumference, diameter, deformation, volume and internal pressure were compared and analyzed. Results: With the increase of cooling rate, the freezing temperature and freezing time of apple cells decreased gradually. The morphological parameters of apple cells changed with the increase of cooling rate, and the change trend was the same. Conclusion: The optimum cooling rate of apple cells was 10 ℃/min.

60. Invariants of partitions and representative elements

Author

Shou, Bao and Wu, Qiao

Subjects
Mathematics - Combinatorics
Abstract

The symbol invariant is used to describe the Springer correspondence for the classical groups by Lusztig. And the fingerprint invariant can be used to describe the Kazhdan-Lusztig map. They are invariants of rigid semisimple operators described by pairs of partitions $(\lambda^{'}, \lambda^{"})$. We construct a nice representative element of the rigid semisimple operators with the same symbol invariant. The fingerprint of the representative element can be obtained immediately. We also discuss the representative element of rigid semisimple operator with the same fingerprint invariant. Our construction can be regarded as the maps between these two invariants., Comment: 12 pages, 15 figures. arXiv admin note: text overlap with arXiv:1711.03443

61. Fingerprint Invariant of Partitions and Construction

Author

Shou, Bao and Wu, Qiao

Subjects
Mathematics - Combinatorics
Abstract

The fingerprint invariant of partitions can be used to describe the Kazhdan-Lusztig map for the classical groups. We discuss the basic properties of fingerprint. We construct the fingerprints of rigid partitions in the $B_n$, $C_n$, and $D_n$ theories. To calculate the fingerprint of a rigid semisimple operator $(\lambda^{'};\lambda^{"})$, we decompose $\lambda^{'}+\lambda^{"}$ into several blocks. We define operators to calculate the fingerprint for each block using the results of fingerprint of the unipotent operators., Comment: 23 pages,30 figures

63. Factors Affecting Campus Loans in Western China

Author

Zhang, Chengfeng, Wu, Qiao, Wang, Huijuan, Luo, Xia, Wei, Ning, Pan, BingYu, and Tong, Jiajun

Abstract

Campus loans have become a part of the lives of Chinese college students. While such loans are convenient for students, they can also create considerable difficulties. In the context of unbalanced economic development between Western and Eastern China, this study aimed to understand the factors affecting the campus loan behaviors of college students in Western China. A sample of 568 undergraduate and graduate students from four universities in Western China was taken as the research object. Binary logistic regression and orderly logistic regression were used to study campus loan consumption factors. Students without state-subsidized loans were found to have stronger campus loan consumption intention and higher loan amounts, and recreational consumption was the main loan purpose. The factors affecting campus loan consumption included students' family structure, parents' education level, peer students' consumption status, grade level, relationship status, and ability to assess loan risk. Based on the findings, suggestions are made for managing campus loan behavior from the perspectives of the individual, family, school, and government. This study can provide guidance for standardizing campus loans and adjusting college students' consumption attitudes and behaviors.

74. Construction of the Symbol Invariant of Partition

Author

Shou, Bao and Wu, Qiao

Subjects
Mathematics - Combinatorics
Abstract

Symbol is used to describe the Springer correspondence for the classical groups. We prove two structure theorems of symbol. We propose a construction of the symbol of the rigid partitions in the $B_n$, $C_n$, and $D_n$ theories. This construction is natural and consists of two basic building blocks. Using this construction, we give closed formulas of symbols for the rigid partitions in the $B_n, C_n$, and $D_n$ theories. One part of the closed formula is universal and other parts are determined by the specific theory. A comparison of between this closed formula and the old one is made. Previous results can be illustrated more clearly by this closed formula., Comment: 27 pages

Abstract

Applicable anode with an industrial‐compatible production process, high capacitance, and good stability is of great importance for the development of lithium‐ion battery technology. In this work, a composite of carbon/silicon with a well‐reserved void is prepared. The composite shows uniform spherical morphology with rich inside voids between the silicon core and carbon shell. Benefiting from the porous structure, the volumetric variation of silicon in the composite as anode during the charging/discharging process can be reversible, and its good anode stability can be achieved in comparison with carbon‐coated silicon without void. The gravimetric capacitance of it reaches 1579.5 mAh g−1. After 100 cycles, the capacitance retention achieves 91.7% compared with 79.8% of carbon‐coated silicon without void. [ABSTRACT FROM AUTHOR]

97. Full-length GSDME mediates pyroptosis independent from cleavage

Abstract

Gasdermin (GSDM) family proteins, known as the executors of pyroptosis, undergo protease-mediated cleavage before inducing pyroptosis. We here discovered a form of pyroptosis mediated by full-length (FL) GSDME without proteolytic cleavage. Intense ultraviolet-C irradiation-triggered DNA damage activates nuclear PARP1, leading to extensive formation of poly(ADP-ribose) (PAR) polymers. These PAR polymers are released to the cytoplasm, where they activate PARP5 to facilitate GSDME PARylation, resulting in a conformational change in GSDME that relieves autoinhibition. Moreover, ultraviolet-C irradiation promotes cytochrome c-catalysed cardiolipin peroxidation to elevate lipid reactive oxygen species, which is then sensed by PARylated GSDME, leading to oxidative oligomerization and plasma membrane targeting of FL-GSDME for perforation, eventually inducing pyroptosis. Reagents that concurrently stimulate PARylation and oxidation of FL-GSDME, synergistically promoting pyroptotic cell death. Overall, the present findings elucidate an unreported mechanism underlying the cleavage-independent function of GSDME in executing cell death, further enriching the paradigms and understanding of FL-GSDME-mediated pyroptosis.
