Arrays of highly ordered n-type silicon nanowires (SiNW) are fabricated using complementary metal-oxide semiconductor (CMOS) compatible technology, and their applications in biosensors investigated. Peptide nucleic acid (PNA) capture probe-functionalized SiNW arrays show a concentration-dependent resistance change upon hybridization to target DNA that is linear over large dynamic range with detection limit 10 fM. As other biosensing devices, the sensing mechanism can be understood terms...
The development of a sensing platform with high sensitivity and specificity, especially programmability universal applicability, for the detection clinically relevant molecules is highly valuable disease monitoring confirmation but remains challenge.

Robustness is one of the most important performance criteria for any rail transit network (RTN), because it helps us enhance efficiency RTN. Several studies have addressed issue RTN robustness primarily from perspectives given structures or static distributions passenger flow. An open problem that remains in fully understanding how to take spatio-temporal characteristics travel into consideration, since dynamic flow an can readily trigger unexpected cascading failures. This paper addresses...
Exploring novel systems with perpendicular magnetic anisotropy (PMA) is vital for advancing memory devices. In this study, we report an intriguing PMA system involving ultrathin Fe layer on antiferromagnetic (AFM) CoO(001) surface. The measured field inversely proportional to the thickness, indicating interfacial origin of PMA. Temperature-dependent measurements reveal that antiferromagnetism CoO has a negligible effect By leveraging magneto-optic Kerr and birefringence effect, achieve...
Sequence-specific DNA detection is a routine job in medical diagnostics and genetic screening. Alternative to fluorescence readout scheme or electrophoresis approach, various kinds of rapid, low-cost, facile, label-free methods have also been developed last decades. Among these, direct electrical received increasing attention but more research desirable. Particularly, enhancement with high discrimination must be employed selectively amplify the responding signal. A chip-based biosensor was...
The robustness is a crucial and essential problem of subway network (SN), which can help us improve the efficiency transportation system. Several existing researches have analyzed SN based on rail structure or static distribution passenger flow. However, spatiotemporal characteristic flow also plays an important role in robustness, since it trigger some unexpected cascading failures SN. Therefore, how to characterize effect this failure still remains open problem. In paper, we address above...

Abstract We propose and investigate a phase‐shifted long‐period fiber grating (LPFG) written by CO 2 laser in twisted single‐mode fibers (SMFs).For the beating effect, two peaks of LPFG derived from phase‐shift further split into peaks, respectively. The evolution characterization transmission spectra were investigated. channel spacing LPFGs Er‐doped could be much narrower than that which normal SMF. Polarization dependent loss beat‐gratings is less 0.6 dB. This type gratings provides...

Spatial-frequency division multiplexing (SFDM)/coarse-wavelength (CWDM) of in-line fiber-optic etalon (ILFE) strain sensors, formed by a section hollow-core photonic crystal fiber (HCPCF), is reported in this paper, for the first time to best our knowledge. Due low thermal expansion coefficient HCPCF, such sensor much less sensitive temperature change compared with conventional ILFE sensors. In meanwhile, as transmission loss HCPCF very low, cavity length can be longer than existing ILFEs,...
