A Novel Steganography Method for Infrared Image Based on Smooth Wavelet Transform and Convolutional Neural Network.

Infrared images have been widely used in many research areas, such as target detection and scene monitoring. Therefore, the copyright protection of infrared images is very important. In order to accomplish the goal of image-copyright protection, a large number of image-steganography algorithms have been studied in the last two decades.

Preparation of Polyoxometalate-Based Composite by Solidification of Highly Active Cobalt-Containing Polytungstate on Polymeric Ionic Liquid for the Efficient Isolation of Proteinase K.

A novel porous polyoxometalate (POM)-based composite (CoPW-PDDVAC) was prepared via the solidification of water-soluble polytungstate (CoPW) on the polymeric ionic liquid dimethyldodecyl-4-polyethylene benzyl ammonium chloride (PDDVAC) via a cation-exchange reaction. The solidification was confirmed by EDS, SEM, FT-IR, TGA, and so on. The strong covalent coordination and hydrogen-bonding interaction between the highly active Co of the CoPW and the aspartic acid residues of proteinase K endowed the obtained CoPW-PDDVAC composite with excellent proteinase K adsorption properties.

Fluorescent Imaging Probe Targeting Mitochondria Based on Supramolecular Host-Guest Assembly and Disassembly.

Fluorescent dyes and probes play an indispensable role in bioimaging. The mitochondrion is one of the crucial organelles which takes charge of energy production and is the primary site of aerobic respiration in the cell. To illuminate mitochondria, a series of supramolecular fluorescent imaging probes were developed based on the host-guest assembly of 1,4-bis[2-(4-pyridyl)ethenyl]-benzene (BPEB) derivatives and cucurbituril[6] (CB[6]).

Achieving 3D Beamforming by Non-Synchronous Microphone Array Measurements.

Beamforming technology is an essential method in acoustic imaging or reconstruction, which has been widely used in sound source localization and noise reduction. The beamforming algorithm can be described as all microphones in a plane simultaneously recording the source signal. The source position is then localized by maximizing the result of the beamformer.

An Adaptive Autogram Approach Based on a CFAR Detector for Incipient Cavitation Detection.

Cavitation failure often occurs in centrifugal pumps, resulting in severe harm to their performance and life-span. Nowadays, it has become crucial to detect incipient cavitation ahead of cavitation failure. However, most envelope demodulation methods suffer from strong noise and repetitive impacts.

[Growth-promotion and disease control effects on chili and eggplant by arbuscular mycorrhizal fungi and plant symbiotic actinomycetes].

Arbuscular mycorrhizal fungi (AMF) or plant symbiotic actinomycetes (PSA) play an important role in stimulating plant growth, antagonizing pathogens, tolerating stress, and controlling plant disease. However, whether there is a synergistic effect between AMF and PSA in promoting plant growth and controlling disease is worth exploring. The aim of this study was to evaluate the effects of AMF and PSA on growth-promotion and controlling disease on Solanaceae vegetables and to obtain effective AMF+PSA combinations.

[Arbuscular mycorrhizal fungi enhance cadmium uptake of wetland plants in contaminated water].

Arbuscular mycorrhizal fungi (AMF) play an important role in plant growth enhancement, tolerance to heavy metal toxicity, and rehabilitation of contaminated ecosystems. An experiment was carried out with Phragmites communis and Pennisetum alopecuroides inoculated with or without Funneliformis mosseae (Fm), or Rhizophagus intraradices (Ri) under the simulated wetland system with Cd polluted water (0, 5, 10 or 20 mg·L). The results showed that Cd addition significantly decreased mycorrhizal colonization.

Solvent Effects on Gelation Behavior of the Organogelator Based on L-Phenylalanine Dihydrazide Derivatives.

A series of organogelators based on L-phenylalanine has been synthesized and their gelation properties in various organic solvents were investigated. The results showed that these organogelators were capable of forming stable thermal and reversible organogels in various organic solvents at low concentrations, and the critical gel concentration (CGC) of certain solvents was less than 1.0 wt%.

Technical considerations and outcomes for ileal ureter replacement: a retrospective study in China.

Background: Ileal ureter replacement is an alternative treatment for various length ureter defects. We present our experience and outcome of ileal ureter replacement in China.

Methods: We retrospectively collected data of patients who underwent ileal ureter replacement between January 2010 and January 2015.

Remarkable pressure-induced emission enhancement based on intermolecular charge transfer in halogen bond-driven dual-component co-crystals.

A series of two-component co-crystals driven by IN interactions based on the bipyridine (BIPY) chromophore with one among three different co-former building blocks, iodopentafluorobenzene (IPFB), 1,4-diiodotetrafluorobenzene (DITFB) and 1,3,5-trifluoro-2,4,6-triiodobenzene (IFB), were prepared and analysed via infared spectroscopy and single-crystal X-ray diffraction. By comparing the IN distances in the co-crystal structures, we found that the higher the -F ratio in the building blocks the closer the contact of the IN bond, enhancing the intermolecular interactions in these co-crystals as well. That is, the positive electrostatic potential on the iodine atom(s) in the co-formers was enhanced by the presence of strong electron-withdrawing groups.

KLF8 is required for bladder cancer cell proliferation and migration.

Krüppel-like factor 8 (KLF8) belongs to the Sp/KLF family of transcription factors. Recently, it is affirmed that KLF8 plays an important role in the regulation of epithelial-mesenchymal transition, which is a key process that occurs during cancer metastasis. Although the overexpression of KLF8 has been observed in several types of human cancers, the functional role of KLF8 in human bladder cancer remains unknown.

[Rapamycin inhibits the proliferation of prostate cancer cell line 22RV1 and activity of S6K1].

Objective: To explore the effects of rapamycin on the proliferation of prostate cancer cell line 22RV1 and the activity of S6K1.

Methods: Prostate cancer 22RV1 cells cultured in vitro were treated with rapamycin at the concentrations of 0, 50, 100, 200 and 400 nmol/L. The inhibition rate of the cells'proliferation was detected by MTT, and the activity of S6K1 was determined by liquid scintillation counting.

Sequential injection kinetic spectrophotometric determination of quaternary mixtures of carbamate pesticides in water and fruit samples using artificial neural networks for multivariate calibration.

A new analytical method was developed for the simultaneous kinetic spectrophotometric determination of a quaternary carbamate pesticide mixture consisting of carbofuran, propoxur, metolcarb and fenobucarb using sequential injection analysis (SIA). The procedure was based upon the different kinetic properties between the analytes reacted with reagent in flow system in the non-stopped-flow mode, in which their hydrolysis products coupled with diazotized p-nitroaniline in an alkaline medium to form the corresponding colored complexes. The absorbance data from SIA peak time profile were recorded at 510 nm and resolved by the use of back-propagation-artificial neural network (BP-ANN) algorithms for multivariate quantitative analysis.

[A retrospective study of 4865 cases of paroxysmal supraventricular tachycardia treated with catheter ablation].

In recent 10 years, using radiofrequency catheter ablation, our medical center has treated 4865 cases of paroxysmal supraventricular tachycardia (PSVT). To improve clinical practice, a retrospective analysis of this group was made. In this group, 2092 cases were atrioventricular reentry tachycardia (AVRT), including 1415 left accesory pathway and 677 right accesory pathway, and 2773 cases were atrioventricular nodal reentry tachycardia (AVNRT).
