title: Two Cu(II) and Co(II) coordination polymers: crystal structures and treatment activity on human ovarian cancer cells

description: Two new coordination polymers (CPs), namely [Cu(4-bptzp)(1,3-BDC)]<sub>n</sub> (<b>1</b>, 1,3-H<sub>2</sub>BDC = 1,3-benzenedicarboxylic acid, 4-bptzp = 1,4-bis(5-(4-pyridyl)tetrazolyl)propane) and [Co(4-bptzh)(1,3-BDC)]<sub>n</sub> (<b>2</b>, 4-bptzh = 1,4-bis(5-(4-pyridyl)tetrazolyl)hexane) were prepared by hydrothermal reactions of the corresponding metal salts with the 1,3-H<sub>2</sub>BDC in the presence of different flexible bis(pyridyl-tetrazole) ligands. The inhibitory effect of compounds <b>1</b> and <b>2</b> on SK-OV-3 human ovarian cancer cells was assessed. Firstly, the CCK-8 assay was performed and the anti-proliferation activity of compounds <b>1</b> and <b>2</b> was assessed. Then, the Annexin V-FITC/PI apoptosis assay was performed to detect the apoptosis of the cancer cells in flow cytometry.

title: Synthesis, structure, spectra, magnetism, non-linear optical properties and DFT calculations of a bis(dithiolene)nickel(III) anion salt with substituted isoquinolinium

description: Self-assemble of the bis(maleonitriledithiolate)nickel(III) anion ([Ni(mnt)<sub>2</sub>]<sup>−</sup>) and 4-cyanobenzyl isoquinolinium cation ([4CNBzIQl]<sup>+</sup>) results into a new molecular solid, [4CNBzIQl][Ni(mnt)<sub>2</sub>](1). Single crystal X-ray diffraction revealed that contains segregated columns of anions and cations and the Ni(III) ions form a 1 D zigzag alternating chain through Ni···S and π···π interactions between anions. Powder XRD diffraction study confirms the crystalline nature of the title material. The UV-Vis spectral analysis was used to determine the band gap energy, and the nonlinear optical (NLO) effect of the compound was predicted using DFT. Upon the temperature is lowered, the non-uniform chain has been compressed with the change of Ni···Ni distance, and a spin gap transition around 128 K.

description: The six-rotor UAVs are becoming more susceptible to system or component faults, therefore, to ensure various components of the UAV operate reliably and give full play to its benefits, it is necessary to develop fault diagnosis. In this dataset called CFT-SOM, the flight data used for the micro fault detection of the six-rotor UAV motor is provided. This set of data is made up of three categories, the first is original flight data, the second is the frequency domain data processed by the CFT algorithm, and the third is the necessary result information obtained after the frequency domain data is trained by the SOM network.

title: Applying frequent-pattern mining and time geography to impute gaps in smartphone-based human-movement data

description: Though GPS-based human trajectory data have been commonly used in travel surveys and human mobility studies, missing data or data gaps that are intrinsically relevant to research reliability remain a critical and challenging issue. This study proposes a novel framework for imputing data gaps based on frequent-pattern mining and time geography, which allows for considering spatio-temporal travel restrictions during imputation by evaluating the spatio-temporal topology relations between the space-time prisms of gaps and corresponding frequent activities or trips. For the validation, the proposed framework is applied to raw GPS trajectories that were collected from 139 participants in Switzerland. In the case study, the temporal and spatio-temporal gaps are artificially generated by randomly choosing activities and trips from the trajectory data. Through comparing the mobility indicators (i.e. duration and distance) calculated from raw data, imputed data, and data with gaps, we quantitatively evaluate the performance of the proposed method in terms of Pearson correlation coefficients and deviation. We further compare the framework with the shortest path interpolation method based on the generated spatio-temporal gaps. The comparison results demonstrate the performance and advantage of the proposed method in imputing gaps from GPS-based human movement data.<br>
