Finding poly(amidoxime) (PAO) based adsorbent with better performance in U(VI) extraction from seawater is a hot research topic. By employing plasma treatment, the bi-functionalized adsorbents containing amidoxime and phosphate (labelled as PO4/PAO) were successfully synthesized. The obtained PO4/PAO was characterized and applied for the potential extraction of U(VI) from aqueous solution. The results show that −PO4 enhanced the hydrophilicity of PAO. PO4/PAO possesses good selective sorption ability for U(VI) and excellent reusability. The findings is helpful to understand optimizing performance of PAO based adsorbents for uranium extraction from seawater.

We evaluated differences in ascorbic acid (AsA) and glutathione (GSH) contents and activities of enzymesinvolved in the AsA metabolism in fruits of 20 cultivars of Chinese persimmon (Diospyros kaki). The total AsAcontent ranged from 3.85 (cv. Yangshuohuoshi) to 83.02 μmol·g-1 FW (cv. Wangmoshuishi), with an average of 36.69μmol·g-1 FW across the 20 cultivars. The total GSH content ranged from 0.205 (cv. Yangshuohuoshi) to 0.815 μmol·g-1 FW(cv. Mimiguan) with an average 0.533 μmol·g-1 FW. There were significant differences in activities of dehydroascorbatereductase (DHAR, EC 1.8.5.1), monodehydroascorbate reductase (MDHAR, EC 1.6.5.4), ascorbate peroxidase (APX,EC 1.11.1.11), and glutathione reductase (GR, EC 1.6.4.2) in fruits among the 20 cultivars. The AsA content wassignificantly positively correlated with MDHAR and DHAR activities, but not with GSH and hydrogen peroxide(H2O2) contents or APX activity. These results indicated that both MDHAR and DHAR, especially MDHAR, playimportant roles in maintaining the AsA redox state by reducing oxidized AsA back to AsA and the AsA level mainlydepends on biosynthesis, rather than recycling.
A Bi-Target Based Mobile Relay Selection Algorithm for MCNs
( Huijun Dai ),( Xiaolin Gui ),( Zhaosheng Dai ),( Dewang Ren ),( Yingjie Gu ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.11
Multi-hop cellular networks (MCNs) reduce the transmit power and improve the system performance. Recently, several research studies have been conducted on MCNs. The mobile relay selection scheme is a rising issue in the design of MCNs that achieves these advantages. The conventional opportunistic relaying (OR) is performed on the single factor for maximum signal-to-interference-plus-noise ratio (SINR). In this paper, a comprehensive OR scheme based on Bi-Target is proposed to improve the system throughput and reduce the relay handover by constraining the amount of required bandwidth and SINR. Moreover, the proposed algorithm captures the variability and the mobility that makes it more suitable for dynamic real scenarios. Numerical and simulation results show the superiority of the proposed algorithm in both enhancing the overall performance and reducing the handover.
Shelf Life Prediction of ‘Royal Gala’ Apples Based on Quality Attributes and Storage Temperature
Mengke Cao,Dong Wang,Lingyu Qiu,Xiaolin Ren,Huiling Ma 한국원예학회 2021 원예과학기술지 Vol.39 No.3
Phenotypic changes caused by postharvest deterioration of the quality attributes of apples cause substantial economic losses. Thus, strategies for accurate prediction of the shelf life of apples is urgently needed. In each of the three consecutive years from 2016 to 2018, freshly harvested ‘Royal Gala’ apples were stored at 0, 5, 15, and 25°C, respectively. Subsequently, 11 quality attributes were measured at periodic intervals until the end of storage. To screen fewer and more useful indexes, three input datasets were considered: temperature, color value (L*, a*, b*, △E, and C*), weight loss, firmness, titratable acidity, soluble solids content, starch, and reducing ascorbic acid (D1). The key quality attributes were screened by sparse principal component analysis (SPCA) (D2) and correlation analysis (CA) (D3), using shelf life as the output layer of the artificial neural network based on the back propagation (BP ANN) model. The results showed that the correlation coefficients (r) of the predicted and measured shelf life for D1, D2, and D3 were 0.996, 0.997, and 0.993, respectively, while the mean relative errors were 0.071, 0.074, and 0.074, respectively. Meanwhile, the relative percent root mean square (RMS) values were 0.088, 0.092, and 0.112, respectively. The application of SPCA reduced the quality attributes for the input dataset from 12 to 6. Therefore, SPCA-BP ANN was shown to be a useful model for accurate prediction of the postharvest shelf life of ‘Royal Gala’ apples.

Zn1-xCoxO (0 x 0.15) anode material was prepared by an easy polyacrylamide assisted sol-gel route. The successful replacement of Zinc by Cobalt within Cobalt content x 0.09 was confirmed by structural characterization. The introduction of Cobalt element greatly improved the electro-chemical performances of the matrix Zinc oxide. Without carbon coating, at the 20th cycle, Zn0.91Co0.09O anode still preserved a capacity a little bit more than 1000 mA h g1 and a capacity more than 600 mA h g1 was retained at the end of the 50th cycle. Better rate capability was also witnessed. The SEM, EIS at OCV, CV and in situ XRD were further carried out to elucidate the lithiation mechanism. The role Cobalt doping played can be summarized as follows: the stabilization of the Li2Zn phase, the minimization of charge transfer resistance and the enhanced reversibility of the reduction from metal oxide to metal.

Self-supported non-noble metal based bifunctional electrocatalysts with high catalytic activity and long-term stability in awide pH range are highly essential for the production of hydrogen and oxygen, remains a great challenge. Herein, a bifunctional electrocatalyst is synthesized via electroless plating of FeCoNiP nanoparticles on self-supported phosphorus-dopedvertically aligned graphene arrays (FeCoNiP/P-VG). FeCoNiP/P-VG exhibits an exceptionally high catalytic activity forhydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in a wide pH range, with an overpotential of 81and 141 mV for HER, and 240 and 409 mV for OER, in 1.0 M KOH and 0.5 M H2SO4 respectively, at current density of10 mA. It also performs quite low Tafel slope value of 40 mV·dec−1 for HER and 69 mV·dec−1 for OER in 1.0 M KOH. More importantly, it shows prominent stability in acidic and alkaline electrolytes. This study may open a new avenue for thedesign and fabrication of self-supported bifunctional electrocatalysts for water splitting.

Background: Cleidocranial dysplasia (CCD) is a rare genetic disorder affecting bone and cartilage development. Clinical features of CCD comprise short stature, delayed ossification of craniofacial structures with numerous Wormian bones, underdeveloped or aplastic clavicles and multiple dental anomalies. Several studies have revealed that CCD development is strongly linked with different mutations in runt-related transcription factor 2 (RUNX2) gene. Objective: Identification and functional characterization of RUNX2 mutation associated with CCD. Methods: We performed genetic testing of a patient with CCD using whole exome sequencing and found a novel RUNX2 frameshift mutation: c.1550delT in a sporadic case. We also compared the functional activity of the mutant and wild-type RUNX2 through immunofluorescence microscopy and osteocalcin promoter luciferase assay. Results: We found a novel RUNX2 frameshift mutation, c.1550delT (p.Trp518Glyfs*60). Both mutant RUNX2 and wild-type RUNX2 protein were similarly confined in the nuclei. The novel mutation caused abrogative transactivation activity of RUNX2 on osteocalcin promoter. Conclusions: We explored a novel RUNX2 deletion/frameshift mutation in a sporadic CCD patient. This finding suggests that the VWRPY domain may play a key role in RUNX2 transactivation ability.
