Abstract The challenging task of handwriting style synthesis requires capturing the individuality and diversity of human handwriting. The majority of currently available methods use either a generative adversarial network (GAN) or a recurrent neural network (RNN) to generate new handwriting styles. This is why these techniques frequently fall short of producing diverse and realistic text pictures, particularly for terms that are not commonly used. To resolve that, this research proposes a novel deep learning model that consists of a style encoder and a text generator to synthesize different handwriting styles. This network excels in generating conditional… More >

Abstract Transplanting rice varieties grown in different seasons can lead to different yields due to different dry matter production. Early-season rice varieties transplanted in the late season can obtain high yields with short-growth duration and higher yields driven by higher dry matter production. To make clear the variations in dry matter production across seasons, four early-season rice varieties were chosen for late-season transplantation. The grain yield, dry matter accumulation, leaf photosynthetic, and leaf stomatal properties were studied. It was observed that the average yields of these four varieties in the late season were 33% greater, despite… More >

Abstract Voice portrait technology has explored and established the relationship between speakers’ voices and their facial features, aiming to generate corresponding facial characteristics by providing the voice of an unknown speaker. Due to its powerful advantages in image generation, Generative Adversarial Networks (GANs) have now been widely applied across various fields. The existing Voice2Face methods for voice portraits are primarily based on GANs trained on voice-face paired datasets. However, voice portrait models solely constructed on GANs face limitations in image generation quality and struggle to maintain facial similarity. Additionally, the training process is relatively unstable, thereby… More >

Abstract Many phytochemicals and their derived metabolites produced by plants are extensively employed in commercial goods, pharmaceutical products as well as in the environmental and medical fields. However, these secondary metabolites obtained from plants are in low amounts, and it is difficult to synthesize them at the industrial level. Despite these challenges, they may be utilized for a variety of medicinal products that are either available in the market or are being researched and tested. Secondary metabolites are complex compounds that exhibit chirality. Further, under controlled conditions with elicitors, desired secondary metabolites may be produced from More > Graphic Abstract

Abstract Plasticizers are essential additives in the processing of polyvinyl chloride (PVC), with phthalate plasticizers being widely used. However, these conventional plasticizers have been shown to be harmful to human health and environmentally unfriendly, necessitating the exploration of eco-friendly bio-based alternatives. In this study, Camellia oleifera seed oil, a specialty resource in China, was utilized as a raw material and reacted with 4,4′-Methylenebis(N,N-diglycidylaniline) (AG-80) to synthesize Phenyl Camellia seed Oil Ester (PCSOE). PCSOE was employed as a plasticizer to prepare modified PVC films with varying concentrations, with the conventional plasticizer dioctyl phthalate (DOP) serving as a control.… More >

Abstract The epoxymethcrylate resin (EMBHBCMA) of (2E, 6E)-bis(4-hydroxybenzylidene)-4- methylcyclohexanone(EMBHBC) was synthesized by condensing EMBHBC and methacrylic acid (1:2 mole ratio) by using 1,4-dioxane as a solvent and triethylamine as a catalyst at reflux temperature for 1-5 h to get acid value < 10. The structure of EMBHBCMA was supported by UV-Vis, FTIR, ¹ HNMR and ¹³CNMR spectroscopic techniques. Molecular weights and molecular weight distribution of EMBHBCMA were determined by gel permeation chromatography. EMBHBCMA is thermally stable up to about 300°C and followed two step degradation reactions. Kinetic parameters such as n, Ea, A and ΔS* were determined More >

Abstract The epoxy methacrylate of (2E,6E)-2, 6-bis(4-hydroxybenzylidene)cyclohexanone (EBHBCMA) was synthesized by condensing 0.02 equi. EBHBC, 0.04 equi. methacrylic acid, 50 mL THF as a solvent and 0.2 mL triethylamine as a catalyst at reflux temperature for 1-5 h to get acid value < 10. EBHBCMA showed good solubility in common solvents. The structure of EBHBCMA was supported by UV-Vis., FTIR, 1 H NMR, and 13C NMR spectroscopic techniques. DSC thermogram of EBHBCMA exhibited two endothermic peaks (86.4 and 117.1 °C) and one exothermic peak (142.6°C) due to moisture release, melting and curing of the resin, respectively. More >

Abstract Two kinds of poly quaternary ammonium salts (PQAS) namely PDMC (poly (methacryloxyethyl trimethyl ammonium chloride)), CPAM (methacryloxyethyl trimethyl ammonium chloride / acrylamide copolymer) were prepared. The chemical structures of the PQAS were characterized by Fourier transform infrared (FT-IR), nuclear magnetic resonance (¹ H NMR) spectrum, thermogravimetric analysis (TGA), and scanning electron microscope (SEM). The antibacterial activity of PQAS against three kinds of bacteria and one kind of fungus, was evaluated by the method described in QB/T 2738-2012. Antibacterial tests showed that the antibacterial activity increased with the increase of cationicity and molecular weight on PQAS. It More >

Abstract Functional photoactive polysilane copolymers of poly(methylphenylsilane) (PMPS) and disperse yellow 7 methacrylate (DY7MA) were synthesized using UV-technique. In the same manner functional polysilane copolymers of poly(methylphenylsilane-co-dimethylsilane) (CPS) and disperse yellow 7 methacrylate (DY7MA) were also synthesized. By the UV irradiation polysilanes (PMPS and CPS) give rise to silyl macroradicals which initiate the polymerization of photoactive monomer (DY7MA). The synthesized samples were characterized by FTIR, NMR, and UV-Vis spectroscopy. The molar mass of synthesized photoactive functional polysilane copolymers is of order of 103 gm/mol. They exhibited multimodal optical and photoluminescence functional properties. Optical absorbance was observed… More >
