Junjiang Guo, Shiyun Tang, Lijun Chen, Deju Wei, more

International Journal of Quantum Chemistry > 123 > 7 > n/a - n/a

Accurate thermochemical data of Si_xH_y and Si_xF_y series is a prerequisite for high‐end materials design. In this study, the standard enthalpies of formation (

∆_{f} H^{θ}

) of Si_xH_y and Si_xF_y were calculated from atomization and isodesmic reactions using the composite methods CBS‐QB3, G3, G4, W1U, W1BD, and W2‐F12. Second, their temperature‐dependent thermochemical parameters (∆_𝑓𝑆^θ and C_p) are derived from...

Parental absence, early reading, and human capital formation for rural children in China

Lijun Chen, Fred Wulczyn, Scott Huhr

Journal of Community Psychology > 51 > 2 > 662 - 675

In this study, we adopt the human capital formation framework to understand the association of the various risk and protective factors in the family settings of rural children with their cognitive performance as measured by vocabulary and math test scores. We examine the role of caregiver reading or storytelling to children at younger age and the deprivation of parental care due to labor migration...

Knockdown of replication protein A 3 induces protective autophagy and enhances cisplatin sensitivity in lung adenocarcinoma by inhibiting AKT/mTOR signaling via binding to cyclin‐dependent kinases regulatory subunit 2

Lijun Chen, Ke Hu, Yu Liu, Lingli Liu, more

Drug Development Research > 83 > 7 > 1589 - 1599

Replication protein A 3 (RPA3) is a significant component of replication protein A and has been documented to function as an oncogene in several types of cancers. However, the role and underlying mechanism of RPA3 in lung adenocarcinoma (LUAD) remains unknown. In this study, messenger expression of RPA3 and survival probability in LUAD were predicted by the UALCAN database. The combination of RPA3...

Phenotypic plasticity contributes more to the variations in nutrient resorption than genetic differentiation in a grassland dominant

Zuxin Zhang, Jing Zheng, Yingjie Guang, Lijun Chen, more

Functional Ecology > 36 > 10 > 2605 - 2615

Phenotypic plasticity and genetic differentiation are the two important processes determining the leaf nutrient resorption among and within plant species, which is critical for understanding the adaptability of plants. However, relative contributions of these two processes have never been quantified at a large geographical scale. Here, we investigated intraspecific variations in nutrient resorption...

Double dynamic bonds tough hydrogel with high self‐healing properties based on acylhydrazone bonds and borate bonds

Lijun Chen, Sui Wang, Zhiyong Guo, Yufang Hu

Polymers for Advanced Technologies > 33 > 8 > 2528 - 2541

Hydrogels with excellent self‐healing properties have specific applications in smart polymer materials, but they often do not have excellent mechanical properties, or the preparation process of hydrogels is too complicated. Here, we prepared a multi‐functional intelligent hydrogel using a simple water bath one‐pot method through the synergistic effect of dual dynamic cross‐linked agents, including...

Energy‐aware virtual machine consolidation based on evolutionary game theory

Xialin Liu, Junsheng Wu, Lijun Chen, Lili Zhang

Concurrency and Computation: Practice and Experience > 34 > 10 > n/a - n/a

Cloud data center consumes enormous amount of electrical power resulting in high operating cost and carbon dioxide emission. Virtual machine (VM) consolidation strives to reallocate VMs to the minimum number of physical machines dynamically to reduce energy consumption. An approach is proposed to solve consolidation problem of VMs toward optimization of their energy consumption. A novel algorithm...

Seed germination traits predict seedling emergence rather than survival of Stipa breviflora in populations along a latitude gradient

Zuxin Zhang, Xinping Luo, Dali Chen, Lijun Chen, more

Land Degradation & Development > 32 > 15 > 4417 - 4429

Seed germination is a key stage for successful seedling establishment, and thus it should be considered when selecting the seed source for ecological restoration. However, how seed germination traits of wild species in the laboratory contribute to seedling emergence and establishment under natural conditions is not well known. In this study, seeds from 12 populations collected in 2017 and 14 additional...

Photoswitchable Fluorescent Self‐Assembled Metallacycles with High Photostability

Shangjun Chen, Lijun Chen, Yunsong Cai, Wei‐Hong Zhu

Chemistry – A European Journal > 27 > 16 > 5240 - 5245

In this study, photoswitchable fluorescent supramolecular metallacycles with high fatigue‐resistance have been constructed by coordination‐driven self‐assembly by using bithienylethene with dipyridyl units (BTE) as a coordination donor and a fluorescent di‐platinum(II) (Pt‐F) as a coordination acceptor. The photo‐triggered reversible transformation between the ring‐open and ring‐closed form of the...

On‐chip evolution of combinational logic circuits using an improved genetic‐simulated annealing algorithm

Qianyi Shang, Lijun Chen, Peng Peng

Concurrency and Computation: Practice and Experience > 32 > 23 > n/a - n/a

This paper presents the on‐chip evolution system of combinational logic circuits by a new hybrid algorithm known as improved genetic‐simulated annealing algorithm (IGASA). IGASA is based on the concept and principles of genetic algorithm (GA) and simulated annealing (SA). The main idea is to combine GA's global search ability with the advantage of SA's fast convergence to reach an optimal solution...

EGCG regulates CTR1 expression through its pro‐oxidative property in non‐small‐cell lung cancer cells

Aochang Chen, Pan Jiang, Falak Zeb, Xiaoyue Wu, more

Journal of Cellular Physiology > 235 > 11 > 7970 - 7981

Copper transporter 1 (CTR1) plays an important role in increasing cisplatin intake. Our previous studies showed that CTR1 expression was upregulated by (−)‐epigallocatechin‐3‐gallate (EGCG), a green tea polyphenol, therefore enhanced cisplatin sensitivity in ovary cancer and non‐small‐cell lung cancer (NSCLC) cells. In the current study in the non‐small‐cell lung cancer cells, we uncovered a potential...

Diffuse ultrasonic wave-based structural health monitoring for railway turnouts

Kai Wang, Wuxiong Cao, Lei Xu, Xiongbin Yang, more

Ultrasonics > 2020 > 101 > C

Real-time damage evaluation is a critical step to warrant the integrity of turnout systems in railway industry. Nevertheless, existing structural health monitoring (SHM) approaches, despite their proven effectiveness in laboratory demonstration, are restricted from in-situ implementation in engineering practice. Based upon the continued endeavors of the authors in developing SHM approaches and exploring...

Competitive interaction with keystone taxa induced negative priming under biochar amendments

Lijun Chen, Yuji Jiang, Chao Liang, Yu Luo, more

Microbiome > 2019 > 7 > 1 > 1-18

Background Biochar amendments have been widely proposed as a conventional and efficient strategy to promote soil organic carbon (SOC) sequestration via negative priming. Unfortunately, the extent and biological mechanisms responsible for biochar-induced negative priming are still not fully understood. Despite traditional explanations focused on the environmental filtering mechanisms of biochar amendments...

A Ten‐Step Total Synthesis of Speradine C

Haichao Liu, Lijun Chen, Kuo Yuan, Yanxing Jia

Angewandte Chemie > 131 > 19 > 6428 - 6431

The first total synthesis of speradine C has been achieved in only ten steps from a commercially available 4‐bromoindole. Salient features of the work are the formation of four rings through three cyclizations, namely a bioinspired [3+2] annulation to form the C/D rings, an NCS‐mediated oxidation to construct the E ring, and a Ru‐catalyzed ketohydroxylation to assemble the F ring. This work highlights...

Dynamic analysis of proteomic alterations in response to N‐linked glycosylation inhibition in a drug‐resistant ovarian carcinoma cell line

Jian Shu, Liuyi Dang, Dandan Zhang, Punit Shah, more

The FEBS Journal > 286 > 8 > 1594 - 1605

Glycosylation inhibition can improve the efficacy of antitumor drugs and enhance the apoptosis of cancer cells, thus holding great potential for cancer treatment. Inhibition of N‐glycosylation induces endoplasmic reticulum (ER) stress and the unfolded protein response (UPR), and eventually triggers ER stress‐related apoptosis. Unfortunately, the detailed timeline of these cell responses and protein...
