Holliday junction (HJ) resolution is a fundamental step for completion of homologous recombination. HJ resolving enzymes (resolvases) distort the junction structure upon binding and prior cleavage, raising the possibility that the reactivity of the enzyme can be affected by a particular geometry and topology at the junction. Here, we employed a DNA origami nano-scaffold in which each arm of a H...

In this paper, we demonstrated the shallow NiSiGe Schottky junction on the SiGe P-channel by using low-temperature microwave annealing. The NiSiGe/n-Si Schottky junction was formed for the Si-capped/SiGe multi-layer structure on an n-Si substrate (Si/Si0.57Ge0.43/Si) through microwave annealing (MWA) ranging from 200 to 470 °C for 150 s in N₂ ambient. MWA has the advantage of being diffusion-le...

Neuromuscular junction degeneration is a prominent aspect of sarcopenia, the age-associated loss of skeletal muscle integrity. Previously, we showed that muscle stem cells activate and contribute to mouse neuromuscular junction regeneration in response to denervation (Liu et al., 2015). Here, we examined gene expression profiles and neuromuscular junction integrity in aged mouse muscles, and un...

We report our studies on single-picosecond electrical pulse switching of YBa2Cu3O7−x (YBCO) grain-boundary bicrystal Josephson junctions. The test structures consisted of coplanar strip (CPS) transmission lines that were patterned in 50 nm thick YBCO films prepared on (100) MgO bicrystal substrates. Each CPS contained a 5 μm wide, 10 μm long microbridge and a 5 μm wide grain-boundary Josephson ...

IN THE ABSENCE of functioning anomalous connection between atria and ventricles, the A-V junction serves as the only link between these structures, allowing the atrial impulse to be transmitted to the ventricles. The A-V junction may be defined as consisting of the atrial approaches to the A-V node, the A-V node itself, and the penetrating portion of the His bundle. Total transection of the A-V...

The escape of a current-biased Josephson tunnel junction from the zero-voltage state in the presence of weak microwave radiation is investigated experimentally at low temperatures. The measurements of the junction switching current distribution indicate the macroscopic quantum tunneling of the phase below a crossover temperature of T small star, filled approximately 280 mK. At temperatures belo...

The performance of a five-junction (Nb/AlOx/Nb) array is characterized in the frequency range of 780–950 GHz for different wiring and ground layers of the thin-film microstrip lines of the junction tuning inductance and the associated impedance transformer. Three kinds of thin films (i.e., Nb, Al and NbTiN) are taken for this investigation. The individual SIS junctions of the five-junction arra...

Abstract We theoretically demonstrate that a ferromagnetic/superconductor junction on the surface of three-dimensional topological insulators (3D TIs) has an anisotropic angle-dependent Andreev reflection when in-plane magnetization component perpendicular to junction. In presence magnetization, Dirac cone’s location adjusts in k -space, whereas its out-of-plane induces gap. This movement leads...

Typical superconducting materials have both time-reversal symmetry and inversion symmetry. Devices that break these symmetries are expected to exotic phenomena such as the diode effect, which can provide lossless rectification. Here, we present a device comprising one Josephson junction coupled another exhibits effect. We show observed effect be controlled non-locally based on phase difference ...
