Visual question generation involves the generation of meaningful questions about an image. Although we have made significant progress in automatically generating a single high-quality question related to an image, existing methods often ignore the diversity and interpretability of generated questions, which are important for various daily tasks that require clear question sources. In this paper, we propose an explicitly diverse visual question generation model that aims to generate diverse questions based on interpretable question sources.

The aim of this study was to explore the effects of environmental factors (salt ions and pH) on the thermal gelation process of deamidated soy protein isolate (DSPI). The results indicated that with increasing salt ion concentration, DSPI assembled into larger aggregates, which were more prone to aggregation in thermal reactions, ultimately forming a gel network with higher viscoelasticity. The strength enhancement of ion-induced gel networks followed the order from highest to lowest: Ca > Mg > Na.

Soybean peptide (SP) exhibits significant angiotensin-I-converting enzyme inhibitory (ACEI) activity, however, its strong bitterness restricts its use in food industry. This study aimed to reduce the bitterness of SP by natural deep eutectic solvent (NADES)-driven Maillard reaction (MR). Results showed that both the mixtures of Glucose-NADES and the Glucose-Xylose-NADES formed the hydrogen bonds and shown good thermal stability analyzed by using Fourier transform infrared (FTIR), Differential scanning calorimetry (DSC) and Thermogravimetric analysis (TGA).

Polytrithiocarbonates have attracted significant attention recently because of their good thermal stability, light refractivity, crystallinity, and mechanical properties; however, the exploration of their structures and functionalities has been limited by their synthetic approaches. Multicomponent polymerization featuring simple monomers, mild conditions, diversified product structures, and high efficiency could provide a powerful and versatile tool to synthesize various polytrithiocarbonates from commercially available monomers. Herein, a robust and efficient multicomponent tandem polymerization (MCTP) of CS, dithiols, and alkyl halides was developed in DMF with KCO at room temperature in air to synthesize 12 polytrithiocarbonates with diversified and systematically tuned structures, high molecular weights (s up to 37900 g/mol), and high yields (up to 93%).

Pectin exhibits potential as an excellent food additive for its processing properties and biological activities, but its application is hindered because of complex and unclear structure. Water-insoluble and water-soluble poly-galacturonic acids, hydrolyzed from the spherical pectin from submicroparticles in chrysanthemum tea infusion, were characterized for obtaining the detail structural information. The water-insoluble poly-galacturonic acid was a crystal which constructed by hydrogen bonds and long linear chains comprised of α-1,4-glycosidic bonds and galacturonic acid residues.

In this study, we investigated the effects of infant fecal fermentation-derived metabolites of digested osteopontin (OPN) and 2'-fucosyllactose (2'-FL), either individually or in combination, on intestinal barrier function using a Caco-2/HT-29 coculture cell model. Our results suggested that the OPN/2'-FL (1:36-1:3) cofermentation metabolites improved epithelial barrier integrity by supporting the mRNA and protein expression of occludin, claudin-1, claudin-2, ZO-1, and ZO-2. All of the OPN/2'-FL treatments decreased the production of IL-1β, IL-6, and TNF-α, while the OPN/2'-FL ratio increased IL-10 production by inhibiting activation of the MyD88/IκB-α/NF-κB signaling pathway.

Understanding the interplay among the mechanical behavior, ionic conductivity and chain dynamics of ionogels is essential for designing flexible conductors that exhibit both high conductivity and excellent mechanical properties. In this study, ionogels were synthesized the radical polymerization of ,'-dimethylacrylamide (DMAA) and methacrylic acid (MAAc) monomers in the presence of ionic liquid 1-ethyl-3-methylimidazolium trifluoromethane sulfonate ([EMIM][OTf]). By varying the mass content of ionic liquid within ionogels, we investigated the mechanical behavior and ionic conductivity at the macroscopic scale using tensile, rheological testing and electrochemical impedance spectroscopy, as well as the dynamic behavior of chain segments and ions within the network at the microscopic scale using broadband dielectric relaxation spectroscopy (BDS) over a broad temperature range.

Ferroelectric nematic (N) liquid crystals present a compelling platform for exploring topological defects in polar fields, while their structural properties can be significantly altered by ionic doping. In this study, we demonstrate that doping the ferroelectric nematic material RM734 with cationic polymers enables the formation of polymeric micelles that connect pairs of half-integer topological defects. Polarizing optical microscopy reveals that these string defects exhibit butterfly textures, featured with a 2D polarization field divided by Néel-type kink walls into domains exhibiting either uniform polarization or negative splay and bend deformations.

Endovascular aneurysm repair (EVAR) plays a crucial role in the treatment of abdominal aortic aneurysm (AAA) in the clinic, but the aneurysm remains in the patient's body after surgery, continuing to pose a risk of progression. Cycloastragenol (CAG) is proven to be an effective anti-AAA drug, and its vascular protective effects can be further improved when the hydrophobic CAG is encapsulated into nano-sized formulations to enhance its bioavailability. In this context, this study developed an extravascular patch hydrogel loaded with CAG nanostructured lipid carriers and a hydrophilic drug of doxycycline hydrochloride (DOX).

Antiadhesive coatings have been extensively studied owing to their wide applications in biology, environment, and energy. However, developing a mechanically robust coating with broad-spectrum antiadhesion properties remains challenging. Herein, a novel strategy for preparing hard yet flexible and self-adaptive zwitterionic polysilazane coatings with broad-spectrum antiadhesion properties (anti-biofouling, anti-liquid adhesion, and anti-scaling) is proposed.

Ferroelectric nematic liquid crystals are polar fluids characterized by microscopic orientational ordering and macroscopic spontaneous polarizations. Within these fluids, domain walls that separate regions of different polarizations are ubiquitous. We demonstrate that the π walls in films of the polar fluids consist of twin half-integer surface disclinations spaced horizontally, enclosing a subdomain where the polarization exhibits left- or right-handed π twists across the film.

Two dimensional covalent organic framework (2D COF) films based on triphenylamine are considered to be promising electrochromic and energy-storage materials owing to their interlayer π-π electron delocalization, one-dimensional (1D) nanopores, and stable chemical structures. Triphenylamine-based 2D COF electrochromic films, nevertheless, rarely exhibit transparency and high optical contrast, which severely limited the scope of their application. In this work, two directly grown triphenylamine-based polyimide 2D COF films, TAPA-PMDA and TAPA-NTCDA PI COF, were prepared through solvothermal technology.
