SU(3)C×SU(3)L×U(1

Abstract

We propose the SUð3Þ C × SUð3Þ L × Uð1Þ X model arising from SUð6Þ breaking. One family of the Standard Model (SM) fermions arises from two6 representations and one 15 representation of SUð6Þ gauge symmetry. To break the SUð3Þ C × SUð3Þ L × Uð1Þ X gauge symmetry down to the SM, we introduce three SUð3Þ L triplet Higgs fields, where two of them come from the6 representation while the other one from the 15 representation. We study the gauge boson masses and Higgs boson mass in detail, and find that the vacuum expectation value (VEV) of the Higgs field for SUð3Þ L × Uð1Þ X gauge symmetry breaking is around 10 TeV. The neutrino masses and mixing can be generated via the littlest inverse seesaw mechanism. In particular, we have normal hierarchy for neutrino masses and the lightest active neutrino is massless. Also, we consider constraints from the charged lepton flavor changing decays as well. Furthermore, introducing two SUð3Þ L adjoint fermions, one SUð3Þ C adjoint scalar, and one SUð3Þ L triplet scalar, we can achieve gauge coupling unification within 1%. These extra particles can provide a dark matter candidate as well.

Drug Delivery (Nano)Platforms for Oral and Dental Applications: Tissue Regeneration, Infection Control, and Cancer Management

“…formulations as a biomimetic agent against dental caries [108] and dentin hypersensitivity. [109] Calcium and phosphate-based ion delivery systems such as hydroxyapatite, [110] tricalcium phosphate, [95,111] and amorphous calcium phosphate (ACP) are promising agents for prevention of dental caries by increasing saturation of these ions in the oral environment. [112][113][114] Polyamidoamine (PAMAM) dendrimers are a group of hydrophilic polymers with an ethylenediamine core and amidoamine branching structure that enable them to absorb calcium molecules.…”

Small Molecular Fluorescent Probes for Imaging of Viscosity in Living Biosystems

“…Fortunately, fluorescence imaging is emerging as a robust technique for direct visualization of cell events owing to its outstanding sensitivity, high temporal‐spatial resolution, and noninvasive operation [7–10] . Numerous fluorescent probes for various bioactive species and microenvironments have been reported and utilized to explore physiological and pathological processes [11–23] . Particularly, owing to the easy synthesis and modification as well as excellent repeatability, small molecular fluorescent probes are widely employed [24–27] .…”

Reaction mechanism, cure behavior and properties of a multifunctional epoxy resin, TGDDM, with latent curing agent dicyandiamide

“…It is actually not surprising when one ascribes to the multiplicity and complexity of the epoxy/DICY formulations. According to the reports, [22][23][24][25][26][27][28] the following several reactions were proposed in the curing process of epoxy/DICY system: the ring-opening addition reaction of epoxy ring and primary amine for producing chain growth and secondary amine for building chain branches, etherication of epoxy ring with pendant hydroxyl group, homopolymerization of unreacted epoxy group at higher temperature in the absence of active N-H functionality, addition reaction between nitrile group in DICY and resultant hydroxyl group or excess epoxy group to generate imine and further rearrangement reaction to yield amide. In principle, the above-mentioned reactions may occur, either simultaneously or at different stages of the curing process, depending on the relative reactivity of the components and on the process temperature.…”
