Various π-conjugated copolymers constituted of π-excessive thiophene, selenophene, or furan units (Ar) and π-deficient pyridine quinoxaline (Ar') have been prepared in high yields by the following organometallic polycondensation methods: (i) n X−Ar−Ar'−X + Ni(0)Lm → (-Ar−Ar')-n (X = halogen, zerovalent nickel complex), (ii) X−Ar−X Me3Sn−Ar'−SnMe3 (palladium catalyzed), (iii) a b X−Ar'−X (a b)Ni(0)Lm (-Ar)x(Ar')-y. Powder X-ray diffraction analysis confirms an alternative structure polymer...
We investigate the holographic DC and Hall conductivity in massive Einstein-Maxwell-Dilaton (EMD) gravity. Two special EMD backgrounds are considered explicitly. One is dyonic Reissner-Nordstr$\ddot{o}$m-AdS (RN-AdS) geometry other one hyperscaling violation AdS (HV-AdS) geometry. find that linear-T resistivity quadratic-T inverse angle can be simultaneously achieved HV-AdS models, providing a hint to construct models confronting with experimental data of strange metal future.
Non-small cell lung cancer (NSCLC) remains the most frequently diagnosed and leading cause of cancer-related mortality worldwide. PD-1/PD-L1 axis inhibitors have changed treatment paradigm for various types, including NSCLC. However, success these in clinic is severely limited by their inability to inhibit signaling due heavy glycosylation heterogeneity expression PD-L1 NSCLC tumor tissue. Taking advantage facts that derived nanovesicles could efficiently accumulate homotypic sites innate...
Droplet impact and icing processes are common in nature have broad relevance across various fields. In studying the spreading freezing of water droplets, we found that temperature affects not only process but also dynamics impact. Droplet, surface, ambient temperatures collectively termed composite temperatures. Experiments theoretical results reveal lower suppress spreading, reducing maximum ratio by up to 9.6%. Decreasing reduces droplet inertia, thus slowing motion decreasing area....
Electrically conducting π-conjugated copolymers consisting of π-excessive thiophene-2,5-diyl and π-deficient pyridine-2,5-diyl monomer units show a unique cyclic voltammogram with an unusually large potential difference between the doping undoping peaks, their electronic fluorescence spectra support occurrence intramolecular charge transfer showing absorption peaks at lower energy compared those corresponding homopolymers.
A pronounced effect of overheating is observed on the crystallization behavior for three zirconium-based bulk metallic glasses: Zr41.2Ti13.8Cu12.5Ni10Be22.5, Zr57Cu15.4Ni12.6Al10Nb5, and Zr52.5Cu17.9Ni14.6Al10Ti5. threshold temperature found each alloys, above which there a drastic increase in undercooling level times. Time–temperature-transformation (TTT) diagrams were measured alloys by their respective temperatures. The TTT curves Zr41.2Ti13.8Cu12.5Ni10Be22.5 Zr57Cu15.4Ni12.6Al10Nb5 are...
In this paper we investigate the ratio of shear viscosity to entropy density, $η/s$, in hyperscaling violating geometry with lattice structure. We show that scaling relation violation gives a strong constraint mass graviton and usually leads power law temperature, $η/s\sim T^κ$. find exponent $κ$ can be greater than two such new bound for raised arXiv:1601.02757 is violated. Our above observation testified by constructing specific solutions UV completion various holographic models. Finally,...
We study the Einstein-axions AdS black hole from Born–Infeld electrodynamics. Various DC transport coefficients of dual boundary theory are analytically computed. The electric conductivity depends on temperature, which is a novel property comparing to that in RN-AdS hole. effects Born-Infeld parameter analyzed. Also, we AC electrodynamics with momentum dissipation. For weak dissipation, low frequency behavior satisfies standard Drude formula and coherent for various correction parameter....
We construct charged black hole solutions with hyperscaling violation in the infrared(IR) region Einstein-Maxwell-Dilaton-Axion theory and investigate temperature behavior of ratio holographic shear viscosity to entropy density. When translational symmetry breaking is relevant IR, power law testified numerically at low $T$, namely, $\eta/s\sim T^\kappa$, where values exponent $\kappa$ coincide analytical results. also find that not affected by irrelevant current, but reduced current.
We construct analytical Lifshitz massive black brane solutions in Einstein-Maxwell-dilaton gravity theory. also study the thermodynamics of these and obtain thermodynamical stability conditions. On dual nonrelativistic boundary field theory with symmetry, we analytically compute DC transport coefficients, including electric conductivity, thermoelectric thermal conductivity. The novel property our model is that term supports $z\ensuremath{\ne}1$ such a way coefficients are finite. find...
A high-speed centrifugal pump is the key facility to deliver oil in an aero-engine. The stable operation quite important safety of engine. High-speed stability essentially caused by transient pressure pulsations excited complex flow within pump, which needs be clarified, especially for under a rotating stall condition. In current research, unsteady pulsation and corresponding distribution are analyzed using delayed detached-eddy simulation (DDES) method. Pressure signals extracted monitoring...
We investigate the transport properties within a holographic model characterized by novel gauge-axion coupling. A key innovation is introduction of direct coupling between axion fields, antisymmetric tensor, and gauge field in our bulk theory. This term leads to emergence nondiagonal components conductivity tensor. An important characteristic that off-diagonal elements manifest antisymmetry. Remarkably, behavior this akin Hall conductivity. Additionally, can also achieve metal-insulator transition.

An analytical expression derived for directional cases. It suggests an enhanced temperature uniformity over the samples when with diffuse arranged tetrahedral geometry. This experimentally verified stainless steel beams. Both calculated and determined variations suggest use of geometry would be effective reducing variation...
