Photoactive polymers-decorated Cu-Al layered double hydroxide hexagonal architectures: A potential non-viral vector for photothermal therapy and co-delivery of DOX/pCRISPR
No full textGene and drug co-delivery is considered a promising strategy in combination cancer therapy. In this study, we fabricated Cu-Al layered double hydroxide (LDH) decorated with nanoscale ortho-, meta-, and para-poly(phenylenediamine), and afterward, doxorubicin (DOX) was loaded into nanoparticles. Finally, LDH was wrapped with plasmid CRISPR (pCRISPR). The modified nanohexagonals had particle sizes of approximately less than 100 nm with drug uptake up to 62.3%. pH-responsive nanocarriers exhibited higher cargo release in an acidic environment (pH 5.5) compared to a neutral buffer of pH 7.4. CLSM analysis demonstrated internalization in MEF-7 and HEK-293 cells with high transfection efficiency, further confirming them as promising nanostructures in cargo delivery. Besides, the potential usage of the cell-imprinted technique in order to increase the interactions to the cells, and enhance the cellular internalizations/transfections were assessed and showed a considerable increase (up to 72%) in the cellular internalizations. LDH nanostructures displayed high biocompatibility against HEK-293 and PC12 cells after 24 and 48 h. While they had no significant impact on the viability of MCF-7 cells with the assistance of the cell-imprinted method, these non-viral vectors significantly reduced the viability of HT-29 cells, showing their anti-cancer activity. Ortho, meta, and para forms of the poly(phenylenediamine)s decorated on the surface of the LDH showed transfection efficiencies up to 29.1, 28.2, and 40.1%, respectively. Therefore, this study could be considered the highest record of the pCRISPR delivery using a composite substrate in the literature
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
O(2)/N(2) responsive microgels as functional draw agents for gas-triggering forward osmosis desalination
No full textHigh cost for draw agent recovery during dewatering operation remains challenging for industrial forward osmosis (FO) processes. Hydrogels and microgels have been recently reported as promising draw agents for FO desalination. Aiming to develop an energy-efficient gas-triggering FO desalination process, smart gas-responsive copolymer microgels were developed as draw agents in this study. Functional O2/N2 gas-responsive microgels were synthesised using fluorine monomers of trifluoroethyl methacrylate (FM) or pentafluorostyrene (FS), and water-soluble monomers of diethylaminoethyl methacrylate (DEAEMA), dimethylaminoethyl methacrylate (DMAEMA), hydroxyethyl methacrylate (HEMA) and N-isopropylacrylamide (NIPAM). These microgels become reversibly active to draw water after purging O2 and release the adsorbed water upon N2 purging. Water flux, water recovery and recyclability of microgels were systematically examined in a series of FO operations. Enhanced water flux in FO process can be achieved for the microgels with FM. DEAEMA-FM and DMAEMA-FM microgels provide a high water flux up to 29 LMH for a 2000 ppm NaCl feed at room temperature, while the NIPAM-FM microgels show the best water recovery of 56%. Our results reveal that O2/N2 gas-responsive microgels can be used as emerging smart draw agents for gas-triggering FO desalination.Hesamoddin Rabiee, Bo Jin, Seonho Yun, Sheng Da
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations

Ratio of n-6/n-3 in the diets of beef cattle
No full textEffects of feeding heat-treated canola (C), soybean (S) and flax (F) or mixtures on growth and slaughter characteristics, taste and fatty acid (FA) composition of beef tissue were investigated using 128 crossbred steers to determine the potential of improving the nutritional quality of beef for humans. For Trial 1 (48 steers), dietary treatments were: roasted C, extruded C, roasted S, extruded S, roasted F and extruded F. For Trial 2 (80 steers), the dietary treatments were: S:F (1:1), S:C (1:1), C:F (1:1) and S:F:C (1:1:1), and the oilseeds were processed either by roasting or extruding before mixing. Soybean meal and soybean oil were used to give equivalent lipid and protein contents to each experimental diet. The basal diet consisted of grass silage, barley grain, vitamins and minerals. Steers were fed for a minimum of 100d then slaughtered at a uniform degree of finish. Growth and slaughter characteristics of the steers were only slightly affected by dietary treatment in that the soybean-fed steers consumed more feed and had a higher average daily gain than the canola or flax-fed animals in Trial 1. There was no difference in taste panel parameters for any of the treatments. Inclusion of flax in the diet increased the total n-3 content of meat. Similar results were found for canola and C18:1n-9 although this was not the case for soybean and the n-6 FA. For the n-6 FA in the PL and neutral lipid fractions of the meat samples, levels were correlated with high dietary levels of n-6 or n-9 with low levels of n-3 while for the n-3 FA, levels were correlated with high dietary n-3 levels and low n-6 levels. Oilseed processing method did not have an effect on any fatty acid levels. It is possible to modify the FA composition of beef meat toward a healthier profile by including heat-treated oilseeds in the diet to influence the degree of lipid metabolism in the rumen.ID: S0377840111004007; M3: Article; Accession Number: S0377840111004007; Author: M.A. McNiven (a, ⁎); Author: J.L.
