By means of the nonequilibrium Green function technique, electronic transport through a multiple-quantum-dot system is theoretically studied. In this system, one-dimensional quantum dot chain between two contacts forms main channel for tunneling. Each in couples laterally to dangling dot. Whenever energy incident electron aligned with levels dots, zero point transmission occurs due Fano antiresonance. As result, linear conductance spectrum presents an insulating band around antiresonant...
MXene has excellent anticorrosion and self-lubricating properties. It is widely used in the field of wear resistance. However, there a strong interaction between nanosheets, which makes it easy for them to agglomerate coating affects mechanical properties coating. Thus, application limited. In this study, modified by 2,5-diaminobenzenesulfonic acid, can reduce aggregation functionalized using tetrabutylphosphorus hydroxide benzotriazole lignin composite material (BTA-P4444-Lig) with...

Abstract The intrusion of obstacles onto railway tracks presents a significant threat to train safety, characterized by sudden and unpredictable occurrences. With China leading the world in high-speed rail mileage, ensuring security is paramount. current laser monitoring technologies suffer from high false alarm rates unreliable identification. This study addresses these issues investigating high-resolution technology for obstacles, focusing on key parameters such as range resolution. We...
For a quantum dot (QD) in the Kondo regime, we introduce side QD attached to one of two leads mimic an Anderson impurity conduction electron reservoir. Then, study peculiar effect such double structure. We find that peak local density states QDs exhibits notable deviation from Lorentzian line shape. More importantly, expected linear conductance turns into zero when level or single-particle is aligned with Fermi level. This result indicates presence can quench transport through central QD....
Laser pulse amplification by a high-pressure CO2 amplifier in the long-wave infrared (LWIR) spectral range is feasible technology for strong-field physics research. Crystals such as ZnGeP2 (ZGP) have high nonlinear coefficients and transmittance LWIR region, with widths of generated pulses closely matching gain spectrum amplifiers. Therefore, ZGP optical parametric oscillation (OPO) may allow higher-efficiency energy extraction amplifiers, improving output characteristics systems. In this...
Abstract Magnetization‐prepared 2DFT and 3DFT gradlent echo techniques are presented for acquisition of black blood cardiac images. Both methods incorporate RF pulses saturation, centric or centric‐like view ordering, data during late dlastole, breath‐holding. In a series 13 volunteer studies, these have consistently provided good visuallzation intraventricular structures.
Based on a theoretical model where the nuclear spins remain unchanged during collision, we provide an analytical and general expression for spin state-to-state distribution of ultracold diatom-diatom chemical reaction in magnetic field, given rotational transitions molecules. It simply requires knowledge field-dependent eigenfunctions molecular reactants products reaction. The final drastically changes with field. When is summed over all products, simplified found only required. present...

Excessive sugar consumption is associated with metabolic health problems. Rare sugars are gradually being used as substitutes for sugar, and their increasing daily, raising food-safety issues such false advertising, adulteration, overdosing. The determination of rare-sugar compounds has attracted considerable attention in recent years. However, no standard method the simultaneous six rare (allulose, tagatose, trehalose, isomaltulose, erythritol, mannitol) solid foods available. Therefore,...
By introducing a floating lead to mimic the decoherence mechanism, Fano effect in linear conductance spectrum of T-shaped double quantum dot structure is studied. We find that even case self-energy arising from mechanism much smaller than coupling strength between connected and conducting lead, lineshape can be largely destroyed. In addition, renders high-order electron transmission paths unimportant contributing lineshape.
