Purpose TED (Technology, Entertainment, Design, ) Talks has been one of the most popular video systems. However, the current TED Talks system expressed its inquired videos as in a two-dimensional (2D) table, which is inconvenient for searching the relationships among videos and tags. This study converts the TED Talks table into a sphere by using optimization techniques to help users search for preferred videos. Design/methodology/approach There are five phases in this study as follows. Phase 1: Reorganize data of 36 tags and 108 videos; Phase 2: Allocate tags on the TED sphere; Phase 3: Allocate videos on the TED sphere; Phase 4: Develop an online interactive TED retrieval system; and Phase 5: Perform survey and evaluation. Findings One survey demonstrated that the TED Talks sphere is more convenient for searching videos, as it is more user-friendly because of its graphical user interface, more convenient to use, more useful for retrieving information and can facilitate a more responsive search for users' preferred videos. Research limitations/implications The numbers of tags and videos able to be displayed on a sphere is limited by the capacity of an optimization software and hardware. Practical implications The proposed sphere system can be used by a large number of users of TED Talks groups. Social implications This sphere systems can also be applied to other fields which use 2D forms to display the relationships among objects. Originality/value This study uses an optimization method to convert a 2D form into a 3D sphere to highlight the relationships among numerous objects.

Magnesium alloys have been widely employed in the aerospace and aviation applications due to the unique properties. Nevertheless, Mg alloys were sensitive to corrosion attacks. The use of hexavalent chromium has been strictly banned because of severe toxicity and harm, even though it provided useful protective coating. Many efforts have been made to find the alternative process to hexavalent chromium conversion process. In this study, the Ce / Mn conversion coating was developed on EV31 Mg alloy. A thin, homogeneous, and compact conversion coating layers was formed. The electrochemical impedance spectroscopy (EIS), potentiodynamic polarization tests and salt spray test (SST) were used to evaluate the corrosion resistance of the coatings accompanying with a cross-cut scratches. The total impedance of the Ce/ Mn conversion coating rose to 2.3 x 10(3) Omega.cm(2) compared with 3.4 x 10(2) of the bare EV31. Furthermore, the Ce / Mn conversion coating passed the 168 h of SST with less than 3% corrosion area, and meanwhile the self-healing worked effectively. Both barrier protection and characteristic self-healing effect enhanced corrosion resistance on EV31. Furthermore, a corrosion mechanism for the coating in practice was proposed to discussion.

A method for the catalytic alpha-arylation of indolin-3-ones was developed. The catalytic system comprising Pd(dba)(2) and PAd(3) was found to be optimal for the transformation. The protocol features broad functional group compatibility in that a range of arylated indoxyl derivatives bearing a fully substituted carbon center was synthesized with high efficiency. A preliminary bioassay study revealed that the selected indole-substituted indolin-3-ones exhibit favorable cytotoxic activities against HCT-116 cancer cell line.

Effect of Rainfall, Runoff and Infiltration Processes on the Stability of Footslopes

To analyze the effect of runoff on shallow landslides, a model coupling one-dimensional rainfall-runoff and two-dimensional infiltration was established to simulate rainfall, infiltration, and runoff processes. Based on Bishop's limit equilibrium method, the slope failure of a hypothetical footslope was studied. First, conditions with and without inflow were compared. The results reveal a remarkable difference in factors of safety (FS) between the two conditions, suggesting that considering the effect of runoff is crucial for landslide modeling. In terms of a series of tests of the various magnitudes, durations, lag-time, and peak position of the hydrograph, analyses show that larger inflow leads to more accumulated infiltration and triggers landslides earlier. A long-term duration inflow decreases the stability more than short intensive inflow does. With subsequent surface inflow, slope failure may occur after rainfalls stop, owing to the inflow, and the shape of inflow hydrographs could slightly affect the variance in FS. Results also indicate the necessity of considering the surface runoff when using a numerical model to analyze landslide, particularly on a footslope.

A new fluorescent chemosensor (An3) bearing anthracenyl rings was designed and developed for detection of Zn2+. Addition of Zn2+ into An3 gave rise to a fluorescent turn-on response at 424 nm whereas Al3+, Cd (2+), Co2+, Cu2+, K+, Mg2+, Zn2+, Ca2+, Fe3+, Mn2+, Ni2+, Pb2+, and Hg2+ did not induce any emission intensity enhancement. Furthermore, the probe exhibited high selectivity toward Zn2+ and a very low detection limit (36 nM) based on chelation-enhanced fluorescence. Theoretical calculations revealed the possible formation of 1:1 and 1:2 complexes between An3 and Zn2+. In bioimaging experiments, the chemosensor displayed low cytotoxicity and good biocompatibility, rendering it an effective tool for fluorescent visualization of Zn2+ in living cells and zebrafish models.
