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

... based on T-S fuzzy systems. Then a fuzzy switched strategy is proposed to control the switching actions among subsystems. 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.

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.

... nic Frameworks (MOFs) have been rapidly developed for decades. MOFs are synthesized via the self-assembling combination of inorganic metals and organic ligands, and they have many characteristics superior to the conventional porous materials. The ultrahigh surface area, high porosity, adjustable pore sizes, outstanding thermal and chemical stability enable MOFs to be promising materials for widespread applications. With the deepening of research in recent years, MOFs are successfully applied in diverse fields, such as catalysis, adsorption, separation, and biomedicine imaging, among others. The advances of MOFs used in adsorption and separation are reviewed in this paper, with an emphasis on storage of fuels, carbon capture, membrane separation, liquid-phase adsorption, and chromatographic separation and purification. In addition, the future research directions regarding MOFs in the adsorption and separation field are prospected also.

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.

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

... der has been successfully generated in Er-doped mode-locked fiber laser, exhibiting maximum repetition rate of 1.01 GHz and pulse duration of 940 fs, which to the best of our knowledge, is the highest harmonic mode-locked fiber laser from the MXene SA so far. 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.

... ial lesions of pigs in the defect and repair groups. 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.

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.

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

... erning ribosomal biogenesis and tumor growth was determined. 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.

A compact band-notched ultra-wideband (UWB) spatial diversity antenna is presented in this paper. The antenna is fabricated on an FR4 substrate and consists of two tapered microstrip feeding lines and two radiating elements. The wireless local area network (WLAN) for IEEE 802.11a operating in 5.15-5.825 GHz band-notched function is achieved by introducing two slits in the radiators as λ/4 resonators. The simulated and measured results show that the presented antenna has a broadband impedance

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

... o 90% porosity), but also has excellent superhydrophobic properties (water contact angle up to 153°). 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.
