Abstract The observed flavor-changing neutral-current (FCNC) processes in the standard model (SM) arise from loop diagrams involving weak charged currents mediated by $W$-gauge boson. Nevertheless, top-quark FCNCs and lepton flavor-violating resulting same mechanism are highly suppressed. We investigate possible new physics effects that can enhance suppressed FCNC processes, such as a top quark decaying into light with Higgs or gauge boson final state, i.e., $t\to q(h,V)$ $V=\gamma, Z, g$,...
Epoxy (EP) was copolymerized with polyamic acid (PAA, precursor of polyimide (PI)) termanil monomers (1) 4,4′-Oxydianiline (ODA) and (2) pyromellitic dianhydride (PMDA) individually to form (PI-O-EP) (PI-P-EP) copolymers. The FTIR spectrum PI-O-EP copolymerization intermediates shows that some amide-EP linkages were formed at low temperature broken higher temperature; in additoin, the released amide available for subsequent imidization PI. curing groups on PAA determined by reaction (kinetic...
We have developed a 11.4-inch color active-matrix thin-film transistor (TFT) transparent liquid crystal display (LCD) by using polymer-dispersed (PDLC) technology. The resolution of LCD was designed to wide screen video graphics array (WSVGA) and the pixel per inch (PPI) is 104. Then, transmittance can achieve upward 15%. In this paper, has some advantages, such as, good visibility, high transparency, polarizer free, backlight less (environmental light only), so on.
A novel type of polyimide foams (PIFs) with chemically inserted flexible aliphatic diamine (1,6-diaminohexane (HMDA)) segments was successfully synthesized and characterized in this research. The HMDA were randomly incorporated the long chain aromatic imide bonds. obtained PIFs containing various contents (0 to 20 mol%) exhibited different morphologies such as lowered density larger cell diameter (with higher content), open ratio increased well. rendered flexibility copolymer leading...

We report on the formation of organized sub-micron YBa(2)Cu(3)O(7) (YBCO) dots induced by irradiating femtosecond laser pulses YBCO films prepared pulse deposition with fluence in range 0.21 approximately 0.53 J/cm(2). The morphology film surface depends strongly fluences irradiated. At lower (approximately J/cm(2)) was pattern periodic ripples sub-micrometer spacing. Slightly increasing to 0.26 J/cm(2) changes into diameters ranging from 100 nm 800 and height 150 nm. Further increase over...
The synthesis of LiNbO3-type R3C ZnSnO3 is still a challenging task under an extremely high-pressure condition. In this work, we have not only successfully synthesized nanowires (NWs) through hydrothermal process, but NWs with high concentration oxygen vacancies (referred to as [Formula: see text] NWs), exhibiting highly efficient hydrogen evolution reaction compared unannealed and ZnO NWs. x-ray diffraction pattern Raman spectra both confirm that the as-synthesized mainly belong space group...
In this study, grid-patterned titanium surfaces were induced via nanosecond laser under ambient air. Combined with the surface wettability, ice suppression mechanism of microstructure was analysed by static frost experiments and large droplet freezing experiments. Static frosting used to investigate mechanisms different icing patterns. It is demonstrated that contact properties dynamic will affect resistance freeze surface, respectively. When pulse width 45 ns, forms ordered bulges because...
Time-domain spectroscopy, which probes the dynamics of electronic states near Fermi surface that are associated with superconductivity, has proven to be a powerful method for providing insights into fundamental nature both pseudogap and superconducting gap.

Nevertheless, top-quark FCNCs and lepton-flavor violating resulting same mechanism are highly suppressed. We investigate possible new physics effects that can enhance suppressed FCNC processes, such as $t\to q(h,V)$ with $V=γ,Z,g$, $h\to \ell \ell'$, $\ell\to \ell' γ$. To achieve assumption induced-FCNCs all quantum...
The theory of an independent Higgs field is given by $\textrm{O}(N)$ model with $N$-component scalar $\vec{\phi}$ and a quartic $\lambda(\vec{\phi}\cdot\vec{\phi})^2$ potential when $N=4$. phase structure the can be studied analytically for all values coupling $\lambda$ using large-$N$ limit, both at zero finite temperature. However, authors in 70s 80s argued large $N$ was "sick" "futile", dismissed theory. This based on two points: (1) failure to identify stable phases vacuum (2) issue...

Coherent elastic neutrino-nucleon scattering, challenged by the low nucleus recoil energy of a few tens keV, has been observed COHERENT experiment using targets CsI and Ar. We study contribution light $Z'$ mediator in gauged $U(1)_{L_μ-L_τ}$ symmetry. In contrast to mechanism from kinetic mixing between $U(1)_{\rm em}$ $U(1)_{L_μ-L_τ}$, we adopt dynamical symmetry breaking employing an extra Higgs doublet. As result, weak charge mediated only depends on mass gauge boson. Since two Goldstone...
A unique characteristic of exponentially growing scattering amplitude arises in an anomalous Abelian effective field theory when extremely light Dirac neutrino mass is introduced to break the symmetry. We show that low energy Lagrangian can be made explicitly gauge invariant with help a nonlinear representation Goldstone or Stueckelberg field. study peculiar feature exponential growth ultra-high-energy neutrino-nucleon inelastic scattering. It found cross section highly sensitive ratio...
