Purpose: An omnichannel strategy creates a consistent brand image and customer experience across all channels, making it easier for customers to interact with a business and share information. This research aimed to investigated the relationship between consumers' information-sharing intention and their omnichannel experiences. Research design, data, and methodology: Through an online survey conducted in Vietnam, the study obtained 915 responses. The study used Partial Least Square Structural Equation Modeling (PLS-SEM) to analyze research data and confirm proposed research hypotheses. Results: Research results indicated that information-sharing intention is affected by both online and offline customer experience, and at the same time, the study also confirmed that omnichannel’s three characteristics (integration, individualization, interaction) positively impact on customer experience. Conclusions: From the research result, businesses may boost consumer trust and loyalty with the help of an omnichannel approach, which in turn increases customers' propensity to provide personally identifying information to the firm. One way to do this is to facilitate information exchange by delivering customized and relevant offers. Furthermore, companies show consumers the benefit of providing their data by utilizing it to enhance the customer experience.

Zn2+, Cu2+ and Ni2+ permeabilities through supported liquid membranes (SLMs) were determined experimentally from single, binary, and ternary ionic mixtures. Microporous polypropylene membrane was used as the frame to retain isopar-L solvent and di (2-ethylhexyl) phosphoric acid (D2EHPA) carrier. Sulfuric acid solution was used as a strip (receiving) solution. The ion permeability values were in the 10−7-10−6 cm2 s−1 range and increased with the concentrations of D2EHPA in isopar-L and the stripping sulfuric acid. The ion ideal selectivity ranged from 1.05 (Zn/Cu) to 8.40 (Zn/Ni), depending on the feed concentration. The single ion permeability was significantly higher than the binary mixtures, probably due to ion competition with D2EHPA carrier molecules. High selectivity was achieved using ternary mixtures: Zn2+ was the fast-permeating species due to preferential sorption with D2EHPA. Separating Zn2+ from Cu2+ and/or Ni2+ mixtures was most efficient with high D2EHPA concentration, concentrated H2SO4 strip solution, concentrated feed solution, and from multiple ionic mixes.

This paper presents a fully automatic tool to recognize the liver region from CT images based on a deep learning model, namely Multiple Filter U-net, MFUnet. The advantages of both U-net and Multiple Filters were utilized to construct an autoencoder model, called MFUnet for segmenting the liver region from computed tomograph. The MFUnet architecture includes the autoencoding model which is used for regenerating the liver region, the backbone model for extracting features which is trained on ImageNet, and the predicting model used for liver segmentation. The LiTS dataset and Chaos dataset were used for the evaluation of our research. This result shows that the integration of Multiple Filter to U-net improves the performance of liver segmentation and it opens up many research directions in medical imaging processing field.

<P>Magnetoliposomes (ML) have been emerging as a novel multifunctional nanoparticle with a wide range of biomedical and therapeutic applications over the past decade. Although the ML system has shown excellent performances, the stability and lipid peroxidation of liposomal components are still remaining as key issues and need to be solved for intensive applications. Changing zeta potential of nanoparticles' surface can be seen as a potential way to achieve the stable dispersion. In this work, we have employed the positive charged, abundant and cheap chitosan to coat ML in order to change the zeta potential of the ML system and examined the stability of chitosan@magnetoliposomes (CML) in long-term storage. The combining of pH-sensitive chitosan with temperature-sensitive phospholipid formed a novel pH- and temperature-sensitive nanoparticles which can be promisingly used as controllable drug release applications. These novel CML with chitosan thin shells showed excellent stability in long-term storage; meanwhile, the bare ML sample showed aggregations and forming micrometer-size particles. The CML system can achieve a drug encapsulation efficiency of nearly 50% and an enhanced drug release behavior under pH 5 at 45 degrees C.</P>

Novel highly active visible-light photocatalysts in the form of zinc bismuth oxide (ZnBi2O4) and graphite hybrid composites were prepared by coupling via a co-precipitation method followed by calcination at 450 oC. The asprepared ZnBi2O4-graphite hybrid composites were tested for the degradation of rhodamine B (RhB) solutions under visible-light irradiation. The existence of strong electronic coupling between the two components within the ZnBi2O4- graphite heterostructure suppressed the photogenerated recombination of electrons and holes to a remarkable extent. The prepared composite exhibited excellent photocatalytic activity, leading to more than 93% of RhB degradation at an initial concentration of 50mg·L1 with 1.0 g catalyst per liter in 150min. The excellent visible-light photocatalytic mineralization of ZnBi2O4-1.0graphite in comparison with pristine ZnBi2O4 could be attributed to synergetic effects, charge transfer between ZnBi2O4 and graphite, and the separation efficiency of the photogenerated electrons and holes. The photo-induced h+ and the superoxide anion were the major active species responsible for the photodegradation process. The results demonstrate the feasibility of ZnBi2O4-1.0graphite as a potential heterogeneous photocatalyst for environmental remediation.

The major obstacle of treating cancer patients is acquisition of chemoresistance, in which treated tumor cells become insensitive after chronic drug exposure. To study the mechanism of acquired cisplatin resistance, we established a cisplatin-resistant human gastric cancer cell line. The cisplatin-resistant cell line (YCC-3/R) was isolated after exposing the gastric cancer cell line, YCC-3, to a constant concentration (0.5 ${\mu}g/mL$) of cisplatin for 12 months. The expression of cell cycle regulatory proteins (p53, Bax, p21, p27) in the YCC-3/R were investigated by western blot analysis. The cisplatin treatment significantly down-regulated the p53 and p21 expression level, while up-regulated the p27 expression in the YCC-3/R cells compared to the parental cells. The Bax expression level was similar in both cells. These results suggest that the p27 dependent-cell cycle arrest may prevent cisplatin-induced apoptosis and give enough time to repair the DNA damage in the YCC-3/R cells.

<P>Multifunctional nano-platform for the combination of photo-based therapy and photoacoustic imaging (PAI) for cancer treatment has recently attracted much attention to nanotechnology development. In this study, we developed iron–platinum nanoparticles (FePt NPs) with the polypyrrole (PPy) coating as novel agents for combined photothermal therapy (PTT) and PAI. The obtained PPy-coated FePt NPs (FePt@PPy NPs) showed excellent biocompatibility, photothermal stability, and high near-infrared (NIR) absorbance for the combination of PTT and PAI. In vitro investigation experimentally demonstrated the effectiveness of FePt@PPy NPs in killing cancer cells with NIR laser irradiation. Moreover, the phantom test of PAI used in conjunction with FePt@PPy NPs showed a strong photoacoustic signal. Thus, the novel FePt@PPy NPs could be considered as promising multifunctional nanoparticles for further applications of photo-based diagnosis and treatment.</P><P><B>Electronic supplementary material</B></P><P>The online version of this article (10.1186/s11671-017-2337-9) contains supplementary material, which is available to authorized users.</P>

Using a multinomial logit model with the panel-data set of Vietnam manufacturing firms, this paper investigates the impacts of foreign direct investment (FDI) - small and medium enterprises (SMEs) linkages and other factors on SMEs' participation in the global value chain (GVC). We consider GVC firms are those engaging in any of the three modes including (i) using domestic inputs to export (D2E), (ii) using imported inputs to produce for the domestic market (I2P), (iii) using imported inputs to export (I2E). We discover that FDI-SME linkages statistically encourage Vietnamese SMEs to integrate into the GVC via I2P and I2E, while no statistical association between FDI-SME linkage and D2E participation is found. GVCs participation likelihood is also positively correlated with the introduction of new product introduction. The establishment of firms' production facilities in industrial zones and foreign ownership are both reported to be significantly decisive factors to SMEs' decisions on GVC participation. Besides, there is a strong association between firms' attributes, i.e. employment, capital intensity as well as financial access, and their participation in the GVC. Local governance quality (proxied by the Provincial Competitiveness Index) and the share of skilled labor at the province-level can facilitate firms' integration into GVCs, while greater market concentration may be a hurdle to such potential.

The plating industry is one of the causes of hexavalent chromium Cr (VI) pollution in surface water, raising problems for human health and other living things. In this study, we synthesized CoFe 2 O 4 magnetic nanoparticles and coated them with cetyltrimethylammonium bromide (CTAB), a commonly used cationic surfactant, to form CTAB/CoFe 2 O 4 magnetic nanocomposite for Cr (VI) adsorptive removal application from aqueous solution. Characteristic properties of CTAB/ CoFe 2 O 4 were examined using scanning electron spectrometry, surface area apparatus, X-ray diff ractometer, Fourier transform infrared spectrometry, zeta potential analyzer, and vibrating sample magnetometer. The CTAB/CoFe 2 O 4 had superparamagnetic properties, being easily isolated from an aqueous solution and well regenerated by an external magnet. Besides, the CTAB molecules anchored onto the Co 2 FeO 4 nanoparticle surfaces could increase the positive charge and thus facilitate the electrostatic interaction with the Cr (VI) anions. Accordingly, the CTAB/CoFe 2 O 4 reached the Cr (VI) adsorption effi ciency of 89%, two times higher than the pure CoFe 2 O 4 , at an optimal pH of 2, an adsorbent dose of 1 g/L, and an initial Cr (VI) concentration of 10 mg/L. The CTAB/CoFe 2 O 4 magnetic nanocomposite would promise a high potential for Cr (VI) treatment from plating wastewater with simple separation, good adsorption capacity, and an inexpensive, nontoxic production process.
