Discrete Switched Model and Fuzzy Robust Control of Dynamic Supply Chain Network

Songtao Zhang, Chunyang Zhang, Siqi Zhang, Min Zhang
2018 Complexity  
Supply chain network is more complex and dynamic under the uncertain demand and the lead time. Robustness is a key index of the stable operation for the supply chain network. We investigate a fuzzy robust strategy to realize the robust operation of the supply chain network with the production lead times and the ordering lead times under the uncertain customer demand. A discrete switched model of the dynamic supply chain network with the lead times and the uncertain customer demand is

Furthermore, by introducing the inhibition rate γ, a fuzzy control strategy for the dynamic supply chain network is put forward to suppress the impacts of the lead times and the uncertain customer demand on the operation of the dynamic supply chain network. The fuzzy robust strategy composed of the fuzzy switched strategy and the fuzzy control strategy can guarantee the robust operation of the supply chain network at low cost. Finally, the simulation researches show the advantage of the proposed fuzzy robust strategy through the comparisons with the common robust strategy.

Evaluating the System Compliance in Testing Carbon Nanotube Fibers [article]

Chunyang Jiang, Xin Zhang, Jingna Zhao, Jingyun Zou, Xiaohua Zhang
2017 arXiv   pre-print
System compliances of two testing machines (Keysight T150 and Instron 3365) were studied for the tensile testing of carbon nanotube (CNT) fibers. Due to the different gripping methods, the T150's system compliance was nearly zero, while that of the Instron was nonnegligible. By analyzing the data dispersion with the Weibull theory, a safe gauge length of >10 mm was suggested for CNT fibers. Therefore, a standard test procedure should involve the compliance evaluation, choice of gauge length, and Weibull statistical analysis.

2020 medRxiv   pre-print
Rapid diagnosis of COVID-19 is key to controlling the pandemic. Here we report the potential breath-borne volatile organic compound (VOC) biomarkers for COVID-19. Higher levels of ethyl butanoate were detected in exhaled breath of COVID-19 patients (N=10) than healthy controls/health care workers (N=21), lung cancer (LC) patients (N=7) and backgrounds. In contrast, breath-borne butyraldehyde and isopropanol (an efficient SARS-CoV-2 inactivation agent) were significantly higher for non-COVID-19

COVID-19 patients had lower acetone levels than other subjects, except LC patients. The monitoring of ethyl butanoate, butyraldehyde and isopropanol could lend considerable support in rapidly screening COVID-19; and alerting the presence of COVID-19 patient in particular environments.

2020 Nanophotonics  
AbstractMXene as a novel two-dimensional (2D) material exhibits a lot of advantages in nonlinear optics. However, the common MXene, Ti3C2Tx and Ti2CTx nanosheets, easily suffer from degradation under ambient conditions, greatly limiting their practical applications. Here, we demonstrated one of MXene compounds, V2CTx, which has a strong modulation depth (nearly 50%), can serve as an excellent saturable absorber (SA) in passively mode-locked (PML) fiber lasers. More importantly, 206th harmonic

In addition, the high harmonic order mode-locked operation can maintain at least 24 h without any noticeable change, suggesting MXene V2CTx nanosheets have excellent stability in this mode-locked fiber laser. It is anticipated that the present work can pave the way to new design for MXene-based heterostructures for high-performance harmonic mode-locked lasers.

There were no differences in histological observations (p = 0.081), brain weight (p = 0.063), or indexed brain circumference measurements (p = 0.066) between the groups. COnClusIOn: Closure of cranial defects with a titanium mesh did not limit growth of the cranium or cause abnormal central nervous system development. While there was new bone growth in the cranial defects, the bone was not sufficiently strong to withstand external trauma. ÖZ AmAÇ: Jüvenil insanlar için bir model olarak, büyüyen hayvanlarda kraniyal defektleri doldurmak üzere bir titanyum ağ kullanımını değerlendirmek. yÖntem ve GereÇler: Otuz iki aylık Seghers domuzları üç gruptan birine eşit olarak atandı: kontroller, defekt grubu (tamir edilmemiş 5 x 5 cm lezyonlar) ve tamir grubu (tamir edilmiş 5 x 5 cm lezyonlar). Grupları karşılaştırmak için histolojik değerlendirmeler ve morfolojik ölçümler yapıldı. BulGulAr: Defekt grubundaki iki domuz öldü. Defekt ve tamir gruplarında domuzların kraniyal lezyonlarında yeni kemik oluşumu belliydi. Histolojik gözlemler (p = 0,081), beyin ağırlığı (p = 0,063), veya indekslenmiş beyin çevresi ölçümleri (p = 0,066) açısından gruplar arasında fark yoktu. sOnuÇ: Kraniyal defektlerin titanyum ağ ile kapanması kraniyum büyümesini sınırlandırmadı ve anormal merkez sinir sistemi gelişmesine yol açmadı. Kraniyal defektlerde yeni kemik büyümesi vardı ama bu kemik dış travmaya karşı koymaya yetecek kadar güçlü değildi.

HSPC111 Governs Breast Cancer Growth by Regulating Ribosomal Biogenesis

Changwen Zhang, Chunyang Yin, Lei Wang, Shuping Zhang, Yi Qian, Juan Ma, Zhihong Zhang, Yong Xu, Sijin Liu
2014 Molecular Cancer Research  
Activation of c-Myc plays a decisive role in the development of many human cancers. As a transcription factor, c-Myc facilitates cell growth and proliferation by directly transcribing a multitude of targets, including rRNAs and ribosome proteins. However, how to elucidate the deregulation of rRNAs and ribosome proteins driven by c-Myc in cancer remains a significant challenge and thus warrants close investigation. In this report, a crucial role for the HSPC111 (NOP16) multiprotein complex in

It was discovered that enhanced HSPC111 expression paralleled the upregulation of c-Myc and was directly regulated by c-Myc in breast cancer cells. Knockdown of HSPC111 dramatically reduced the occurrence of tumorigenesis in vivo, and largely restrained tumor cell growth in vitro and in vivo. In stark contrast, HSPC111 overexpression significantly promoted tumor cell growth. Biochemically, it was demonstrated that RNA 3 0 -phosphate cyclase (RTCD1/RTCA) interacted with HSPC111, and RTCD1 was involved in the HSPC111 multiprotein complex in regulating rRNA production and ribosomal biogenesis. Moreover, HSPC111 and RTCD1 synergistically modulated cell growth and cellular size through commanding rRNA synthesis and ribosome assembly coupled to protein production. Finally, overall survival analysis revealed that concomitant upregulation of HSPC111 and RTCD1 correlated with the worst prognosis in a breast cancer cohort. Implications: Inhibition of HSPC111-dependent ribosomal biosynthesis and protein synthesis is a promising therapeutic strategy to diminish breast cancer tumor progression.

Respiratory Adsorption of Organic Pollutants in Wastewater by Superhydrophobic Phenolic Xerogels

Yinchun Li, Depeng Gong, Youliang Zhou, Chaocan Zhang, Chunyang Zhang, Yitian Sheng, Shu Peng
2022 Polymers  
Organogel adsorbents are widely used for the adsorption of hard-to-degrade organic pollutants in wastewater due to their natural affinity to the organic phase in water. In this study, phenolic xerogels (PF) synthesised in the ethylene glycol inorganic acid system are used as a backbone and superhydrophobic phenolic xerogels (ASO-PF) are obtained by grafting aminosilanes onto the PF backbone via the Mannich reaction. The modified ASO-PF not only retains the pore structure of the original PF (up

Owing to the unique pore structure, ASO-PF has excellent compression properties, cycling 50% compression deformation more than 10 times without being damaged, with a maximum compression deformation of up to 80%. A squeeze–suction–squeeze approach is proposed for selective adsorption of organic pollutants in homogeneous solutions based on the recyclable compression properties of ASO-PF. The ASO-PF is put under negative pressure by squeezing, and when the pressure is released, the adsorbed liquid enters the ASO-PF, where the organic pollutants are retained by the adsorption sites in the skeleton, and then the remaining water is discharged by squeezing. This breathing ASO-PF holds great promise for organic pollutant adsorption and recovery applications.
