Plant Science Today

Hydrocarbons have become a serious environmental problem due to industrialization and extensive use of vehicles. Various plant species shows a range of stress responses and adaptations to survive in hydrocarbon stress. This study was conducted to investigate the comparative phytotoxicity of polycyclic aromatic hydrocarbons (PAHs) on plants growing under hydrocarbon stress on the germination and to evaluate the response on seedling growth. For the study, two crop plant species (Brassica juncea L. Czern., and Triticum aestivum L.) and two ornamental plant species (Tagetes erecta L. and Helianthus annuus L.) were taken. Pot experiments were conducted in triplicates of 10 days old seedlings treated with 5, 20, 50 & 100 mg kg -1 concentrations of hydrocarbons. After 20 days, biochemical analysis and antioxidant enzyme activity of these plants were studied. Polyphenol and proline increased with increasing concentration of hydrocarbons which were maximum in H. annuus with 0.909 mg g polyphenol and 0.732 μmol g proline at 100 mg kg. Increase in antioxidant enzymatic activities was observed with increasing concentration. H. annuus showed maximum activity at 100 ppm which was ascorbate peroxidase (20.37 Unit g -1 FW), peroxidase (0.212 Unit g FW) and superoxide dismutase (2.13 Unit g FW). HPLC analysis in plants and soil provided the concentration of hydrocarbons present in plants species after 20 days taken up from the treated soil. Plants cultivated in 100 mg kg concentration were analysed and the lowest toxicity observed in H. annuus which was 3.013 mg kg Naphthalene, 7.750 mg kg Phenanthrene and 5.691 mg kg Anthracene while highest toxicity was observed in Tagetes at 8.476 mg kg Naphthalene, 0.398 mg kg Phenanthrene and 0.416 mg kg Anthracene. These results suggested that H. annuus can be adopted in phytoremediation of hydrocarbons soil.
Perceptual model for adaptive local shading and refresh rate

When the rendering budget is limited by power or time, it is necessary to find the combination of rendering parameters, such as resolution and refresh rate, that could deliver the best quality. Variable-rate shading (VRS), introduced in the last generations of GPUs, enables fine control of the rendering quality, in which each 16×16 image tile can be rendered with a different ratio of shader executions. We take advantage of this capability and propose a new method for adaptive control of local shading and refresh rate. The method analyzes texture content, on-screen velocities, luminance, and effective resolution and suggests the refresh rate and a VRS state map that maximizes the quality of animated content under a limited budget. The method is based on the new content-adaptive metric of judder, aliasing, and blur, which is derived from the psychophysical models of contrast sensitivity. To calibrate and validate the metric, we gather data from literature and also collect new measurements of motion quality under variable shading rates, different velocities of motion, texture content, and display capabilities, such as refresh rate, persistence, and angular resolution. The proposed metric and adaptive shading method is implemented as a game engine plugin. Our experimental validation shows a substantial increase in preference of our method over rendering with a fixed resolution and refresh rate, and an existing motion-adaptive technique.

Laser‐Printing and 3D Optical‐Control of Untethered Microrobots

The two‐photon photo‐polymerization (2PP) method is used to manufacture an articulated micro‐robot for indirect manipulation of cellular structures under laser light. To tackle the stickiness issue between the components of the proposed mechanism, optimizing the contact surface areas is carried out. A step‐by‐step procedure to manufacture and control an untethered articulated micro‐robot under laser light is demonstrated. The manufacture and optical control of a floating multi‐component micro‐mechanism has not been achieved before. This is significant because it is anticipated that the articulated microrobots could be used in complex biomedical applications where control in 3D space is required such as single‐cell analysis, embryo injection, polar‐body biopsy, nuclear transplantation, and multi‐dimensional imaging for microsurgery.

However, the current knowledge of UA and its potential anti-cancer mechanisms and targets in breast cancer cells are limited. In this study, we aimed to illustrate the potential mechanisms and targets of UA in breast cancer cells MCF-7. Methods: The effect of UA on cell growth was determined in MCF-7 cells by MTT assay. The anti-tumor mechanism of UA was evaluated by microarray, CAMP, and Western blot. Moreover, the molecular docking between UA and potential receptors were predicted by iGEMDOCK software. Results: The result of MTT assay demonstrated that UA could inhibit MCF-7 cell growth with IC50 values of 20 μM. Microarray and CMAP analysis, validated by Western blot, indicated that UA significantly modulated IKK/NF-κB, RAF/ERK pathways, and downregulated the phosphorylation level of PLK1 in MCF-7 cells. Conclusion: Our data indicated that the anti-tumor effects of UA are due to the inhibited RAF/ERK pathway and IKK/NF-κB pathway. It could also be explained by the reduced phosphorylation of PLK1 in MCF-7 cells. This study provides a new insight for deep understanding of the new anti-cancer mechanisms of UA in MCF-7 breast cancer cells.

Department of Hepatopancreatobiliary Surgery, The Third Xiangya Hospital, Central South University, Changsha, Hunan, People’s Republic of China Introduction: Chemotherapy resistance is the main cause of poor prognosis in patients with hepatocellular carcinoma (HCC). Therefore, it is important to understand the molecular mechanism of adriamycin (ADM) resistance in HCC. Increasing evidence indicates that circular RNAs (circRNAs) play a crucial regulatory role in different pathological processes. In the current study, we aimed to investigate the roles and the underlying molecular mechanism of circFoxo3 in ADM-resistant HCC. Materials and Methods: Twenty-five pairs of clinical tumors samples and matched normal tissues were collected from patients with HCC. Gainand loss-function experiments were performed to investigate the role of circFoxo3 in ADM-resistant cells. Results: CircFoxo3 expression was increased in ADM-resistant HCC tissues and HCC cell lines and in metastatic tissues compared with non-metastatic tissues. CircFoxo3 knockdown reduces and circFoxo3 overexpression enhances HCC cell invasion and tumor growth. In addition, circFoxo3 interacted with miR-199a-5p and regulated miR-199a-5p expression. Furthermore, ATP Binding Cassette Subfamily C Member 1 (ABCC1) was identified as a new target of miR-199a-5p. CircFoxo3 interacted with miR-199a-5p to positively regulate ABCC1 expression, contributing to epithelial–mesenchymal transition progression. Conclusion: CircFoxo3 knockdown reduces and circFoxo3 overexpression enhances HCC cell invasion and tumor growth through regulation of miR-199a-5p/ABCC1 axis. Our findings reveal that circFoxo3 may be novel biomarkers and therapeutic target for HCC treatment.
Ozone oxidation of β-lactam antibiotic molecules and toxicity decrease in aqueous solution and industrial wastewaters heavily contaminated

ABSTRACT In this work, ozone oxidation of the antibiotics amoxicillin (AMX), cephalexin, and ceftriaxone was investigated in different samples: (i) aqueous solutions (100 mg L−1), (ii) an industrial wastewater containing AMX at 125 mg L−1 (chemical oxygen demand 6000 mg O2 L−1), and (iii) a heavily contaminated industrial wastewater containing the antibiotics at a total concentration of 320 mg L−1. High performance liquid chromatography, molecular absorption spectrophotometry in the ultraviolet/visible region, and total organic carbon measurements showed that ozonation of antibiotics solutions led to removal higher than 95% with 10–20% mineralization. Industrial wastewater also showed very good efficiency for antibiotic removal (80–98%) after ozonation. Moreover, Microtox® test showed 86% toxicity reduction for the industrial wastewater.
Diffusion of Innovation: A Preliminary Assessment of the Perception and Use of Technology in Complex Social Environments

It is clear from current literature that information communication technologies (ICT) will continue to evolve at a rapid pace. As a result, ICT will diffuse into new domains and be used in innovative ways by new groups of people. The research described in this paper presents a point of departure from previous studies because this research was conducted on a new population in a social setting that is unfamiliar to the majority of information systems (IS) researchers and practitioners. In particular, faith-based organizations have become viable economic community enterprises that can truly benefit from ICT. However, these complex social environments have often been overlooked. In order to make a preliminary assessment of the factors that inhibit or facilitate the adoption and use of Information Communication Technologies (ICT) in these complex social environments, the Technology Acceptance Model (TAM) was used to form the intellectual basis of this study. The results revealed that the research population is interested in adopting ICT. However, faith-based organizations lack the financial resources and technical expertise necessary to implement ICT solutions.
The quality Targeting of Cancer Chemotherapy Using Non-Invasive Focused Resonance Nano-Permeabilization

Focused Resonance Nano-permeabilization (FORN) (US Patent 9,616, 245 B2-Apr 11th 2017) enables the 'targeted' delivery of chemo-therapeutic molecules using a safe, non-invasive, whole-body therapeutic device. The prototype device houses a gantry with specialized, near field, radio-frequency (RF) antennae and guns to deliver instantaneous, magnetic resonance. Drug focusing and delivery was enabled using FORN in a patient with advanced, loco-regionally recurrent, metastatic, nasopharyngeal carcinoma (NPC). Nonionizing, safe, extraneous-source radio-frequencies (RF) were delivered in the presence of an instantaneous magnetic field, to create temporary drug molecular weight-specific nanopores in the cell membrane of target lesions, concurrently with systemic chemotherapy. The high frequency RF is timed and delivered to regions of interest (ROIs) to span peak plasma concentrations of infused chemotherapeutic drugs over multiple treatment cycles. FORN-enabled chemotherapy-related adverse event evaluation and tumor response based on PERCIST 1.0 reflected improved clinical, anatomical and metabolic outcomes and significantly reduced myelosuppression in the patient who received 6+1 Cycles of combination chemotherapy, over an extended period of time. Functional Assessment of Cancer Treatment-Head & Neck (FACT-H&N) / Quality of Life (QoL) and Karnofsky Performance Status (KPS) reflected overall patient well-being. Recurrent, loco-regional disease, nodal, hepatic and skeletal metastases showed dramatic response on PET-CT follow up. Concurrent chemo-radiotherapy (CCRT) as a treatment paradigm is the standard of practice in locally advanced nasopharyngeal carcinoma (NPC).
An Ml-Based Memory Leak Detection Scheme for Network Devices

The network is very important to the normal operation of all aspects of society and economy, and the memory leak of network device is a software failure that seriously damages the stability of the system. Some common memory checking tools are not suitable for network devices that are running online, so the operation staff can only constantly monitor the memory usage and infer from experience, which has been proved to be inefficient and unreliable. In this paper we proposed a novel memory leak detection method for network devices based on Machine learning. It first eliminates the impact of large-scale resource table entries on the memory utilization. Then, by analyzing its monotonicity and computing the correlation coefficient with the memory leak sequence sets pre constructed by simulation, the memory leak fault can be found in time. The simulation experiments show that the scheme is computationally efficient and the precision rate is close to 100%, it works well in the actual network environment, and has excellent performance.
Nanoporous gold decorated with silver nanoparticles as large area efficient SERS substrate

Nanoporous gold is a very promising material platform for several plasmonic applications. Nanoporous gold can be formed by dealloying Au–Ag alloys, previously grown by means of Ag-Au co-sputtering. The optical response is completely determined by the nanostructured film features, that only depend on the initial alloy composition. It has been extensively used as SERS substrate both as thin film and nanofabricated fancy designs. Here we explore the potential application of nanoporous gold as SERS substrate as it is coupled and decorated with Ag nanoparticles. Significant enhancement has been observed in comparison with bare nanoporous film.
Substrate by Spray Pyrolysis Technique

In this paper, copper oxide (CuO) thin films were deposited on polyimide plastic substrates by spray pyrolysis technique at different temperatures from 250 to 300°C. All the deposited films were characterized by X-ray diffraction (XRD) technique, ultraviolet (UV)-visible spectrophotometer, and hall effect measurements for the investigation of structural, optical, and electrical properties. The effects of substrate temperature on the structural, optical, and electrical properties of the films were studied. The XRD results revealed that all the CuO films have a facecentered cubic structure. The crystallite grain size was calculated using Scherrer formula and it was found that at the substrate temperature of 300°C, the CuO film presented maximum crystallite grain size of about 81.2 nm. The root mean square (RMS) roughness of the films was measured by scanning tunneling microscopy. RMS was increased with the rise of temperature. The optical transmission measurements by UV-visible spectrophotometer were used to determine the energy gap of the CuO films. Results showed that the optical energy gap has decreased with increasing the substrate temperature. Hall effect measurements showed that all the films are of p-type conductivity. Depending on the substrate temperature, hall measurement showed that the electrical resistivity and carrier concentration are varied from 77.4 Ω cm to 52.7 Ω cm and from 6.3 × 1015 cm−3 to 10.1 × 1015 cm−3, respectively.

A Reliable Artificial Intelligence Model for False News Detection Made by Public Figures

The quick access to information on social media networks as well as its exponential rise also made it difficult to distinguish among fake information or real information. The fast dissemination by way of sharing has enhanced its falsification exponentially. It is also important for the credibility of social media networks to avoid the spread of fake information. So it is emerging research challenge to automatically check for misstatement of information through its source, content, or publisher and prevent the unauthenticated sources from spreading rumours. This paper demonstrates an artificial intelligence based approach for the identification of the false statements made by social network entities. Two variants of Deep neural networks are being applied to evalues datasets and analyse for fake news presence. The implementation setup produced maximum extent 99% classification accuracy, when dataset is tested for binary (true or false) labeling with multiple epochs.
Association of information sharing with the risk and performance of cooperatives’ strategic alliance

Received in 4/20/2018. Ask to Revise on 8/2/2019. Resubmitted on 9/2/2019. Accepted on 10/28/2019 by Dr. Márcia Martins Mendes De Luca (Assistant Editor) and by Dr. Gerlando Augusto Sampaio Franco de Lima (Editor). Published on 12/20/2019. Organization responsible for the journal: Abracicon. Abstract Objective: This study analyzes the association of information sharing with the risk and performance of cooperatives’ strategic alliance, mediated by knowledge sharing and information leakage. Method: A survey research was conducted in agricultural cooperatives listed in the Organization of Brazilian Cooperatives [OCB] (2018), involving managers (manager, supervisor, coordinator and controller) registered in the LinkedIn network. The questionnaire was sent through the SurveyMonkey platform to the 516 managers who accepted the invitation and the final sample totaled 96 valid responses. To test the research hypotheses, the structural equation modeling technique was applied. Results: The results showed that information sharing is directly associated with knowledge sharing, but the association of variables is not observed in the interaction between information sharing and information leakage. Information leakage is directly associated with the risk of the strategic alliance, as is knowledge sharing with alliance performance. Knowledge sharing presented partial mediation in the relationship of strategic alliance risk-information sharing and alliance performance, while information leakage did not meet the mediation requirements. Contributions: The study contributes by highlighting the association of information sharing with knowledge sharing in cooperatives’ collaborative environment. It also provides indications on the consequences of information sharing and information leakage. It also highlights the importance of strengthening strategic alliances to reduce risk and increase performance.
Managing tritium inventory and release with carbon materials in a fluoride salt-cooled high-temperature reactor

The Fluoride Salt-Cooled High-Temperature Reactor (FHR) is an advanced reactor concept, that uses molten-salt coolant and solid-uranium fuel composed of graphite and silicon carbideencapsulated tri-structural isotropic (TRISO) particles. The primary coolant salt is known as flibe (Li2BeF4), which was chosen for its desirable thermal-hydraulic and neutronic properties. Under irradiation, coolant salts containing lithium capture neutrons generating tritium in quantities that are several orders of magnitude larger than the amounts generated by existing light water reactors. Adsorption technology is proposed, using chemically compatible carbon materials for the capture and control of tritium in the FHR. Various nanoporous activated carbon, graphene and nuclear graphite materials have been characterized. This includes the determination of BET surface area, total pore volume, average pore size, and pore size distribution by performing low-temperature gas adsorption experiments and applying microscopic thermodynamic theory. In addition, morphological analysis was conducted with scanning electron microscopy. Hydrogen was used as a surrogate. Its chemisorption on these materials have been measured and modeled at the reactor conditions of 700C and pressures under 4 kPa. Models suggest that the total measured solubility of hydrogen includes a combination of dissociative and molecular adsorption. Carbon materials containing larger volumetric fractions of micropores (width < 2 nm) generally exhibited a higher hydrogen capacity. Further, the presence of micropores was associated with a relatively weak and reversible form of hydrogen chemisorption. At 500 Pa, microporous carbon materials captured 50 times more hydrogen than graphite, which was previously known to be the largest hydrogen sink at reactor conditions. The coupled effects of generation, chemical speciation, adsorption and diffusion of tritium in the FHR system were simulated over 200 full-power days. It was found that an adsorption column using high-performance carbon-based catalyst adsorbed substantial amounts of tritium and reduced the peak release rate from 2400 Ci/day to 40 Ci/day for the 236 MWt FHR. Further, the total tritium inventory in the system decreased by more than 70%, from 68,400 Ci to 19,400 Ci. This demonstrates that adsorption technology can greatly reduce the risk of radiological release during normal operation and reactor transient events.
Multi-shot flash lamp annealing method for electroless-plated Ni-P film on UV-surface-modified ABS

ABSTRACT The multi-shot flash lamp annealing (FLA) method as a rapid annealing technique was developed for an electroless-plated Ni-P film on UV-surface-modified acrylonitrile–butadiene-styrene (ABS) in place of the conventional annealing method. The new multi-shot FLA method continuously irradiates a Xe flash discharge with low irradiance (<1 J cm–2) with a frequency of 3 Hz. An adhesion strength between the electroless Ni-P film and ABS of more than 1.2 kN m–1 was achieved in a short time of approximately 30 s; this adhesion strength was larger than that obtained in the conventional method of 1 h duration. The etching effect of the FLA method was assessed by a study of the surface morphologies of the Ni-P films. XRD spectra of the Ni-P films showed an improvement in the crystallinity of the films. Considering surface elemental analyses of the peeled Ni-P-film/ABS, a cohesive failure, which implies high adhesion, was observed in the ABS. The proposed FLA method is expected to efficiently improve the adhesion and significantly reduce the annealing time in the electroless plating process.
