The number of excavated tunnels is increasing day by day, and the corresponding engineering scale also getting increasing. Safe, efficient, economically beneficial tunnel construction methods are indispensable in process crossing mountains steep ridges southwest region. However, behind improvement transportation infrastructure Southwest China support provided rapid development blasting industry technology China. In using drilling method, addition to vibration disasters phenomenon overbreak...
The realization of a miniaturized spectrometer with high resolution is highly desired but still big challenge. Although all-fiber spectrometers based on speckle detection show their great potential for ones, long fiber lengths set the greatest obstacle design. Here, we demonstrate compact by using cascading coreless fibers and photonic crystal fibers. A unique cascaded structure readily excites more guided modes, in which patterns are formed modal interferences. Using only 10 cm-long...
A high sensitivity optical fiber temperature sensor based on a liquid-filled tapered hollow suspended dual-core (HSDCF) is proposed and experimentally demonstrated. The HSDCF constitute directional coupler. Due to the small distance between cores liquid filled in air hole, resonance coupling occurs two cores. coefficient strongly dependent refractive index of liquid, which causes be very sensitive temperature. Experimental results show that has 38.281 nm/°C within monitorable range 20-26°C....
This Letter proposes a method that balances miniaturization and high performance of fiber optic speckle spectrometers. The periodically tapered coreless is used as the scattering element to excite more higher-order modes in fiber. As result, remarkable spectral resolution 0.03 nm near-infrared spectrum can be achieved with 5-cm-long Narrow linewidth broadband spectra wavelength 1540-1560 are reconstructed separately, demonstrating excellent designed all-fiber spectrometer. our proposed...
We demonstrate a two-dimensional vector bending sensor based on hole-assisted three-core fiber (HATCF) coupler. The is built by splicing section of HATCF between two single-mode fibers (SMFs). resonance couplings the center core and suspended cores occur at different wavelengths. Two completely discrete dips are observed. response proposed investigated over 360° range. curvature direction can be identified interrogating wavelengths dips, maximum sensitivity -50.62 nm/m-1 achieved 0°...
In trees, injuries resulting from subfreezing temperatures can cause damage to the cellular biofilm system, metabolic functions, and fibrous reticulum, even cell death. Investigating occurrence of freezing its contributing factors could help understand mechanisms underlying injury prevent subsequent in trees. To achieve this, a laboratory experiment was conducted using cut wood samples Korean pine ( Pinus koraiensis Siebold & Zucc) Simon poplar Populus simonii Carr.), effects...
We experimentally demonstrate a single mode fiber (SMF) ultrasensitive refractive index (RI) sensor based on long-period grating (LPFG) with periodic microcavities fabricated by femtosecond laser. The liquid in the causes strong RI modulation to excite high-order cladding modes. proposed can operate reflection coating end face of gold film, as result cascade LPFG structure is equivalently formed increase contrast resonance dip. has an ultra-high sensitivity -12576 nm/RIU high linearity range...

NMBs were prepared thin-film hydration method, connected biotin to obtain NMBs-125I complex.36 patients with treated in X Hospital from January December 2019 selected. particle implantation was Computed tomography (CT) or magnetic resonance imaging (MRI) examinations performed 3 months after treatment, divided into...
With the development of IT technologies, an increasing number industrial control systems (ICSs) can be accessed from public Internet (with authentication). In such open environment, cyberattacks become a serious threat to both ICS system integrity and data privacy. As countermeasure, anomaly detection are often deployed analyze network traffic. However, due privacy regulation, packages cannot directly processed in plaintext many countries. this work, we present privacy-preserving platform...
Tunnels are commonly excavated using drilling and blasting methods, the surrounding rock is greatly affected by vibration of hole blasting. To study influence number free surfaces on energy distribution attenuation law signals, on-site experiments numerical simulation were conducted. The research results indicate that higher surfaces, smaller peak velocity. longitudinal Fourier main frequency decreases with distance from monitoring point. more surface, greater centroid zero crossing...

RFID tags are prone to counterfeit attacks in supply chain scenarios. The attacker often uses replace stolen avoid being detected by the inventory process. To defend against such attacks, existing hash-based schemes have know hash functions embedded tags, which usually unavailable large scale systems. This letter proposes a novel group-based slot constraint (GSC) scheme for lightweight tag detection RFID-enabled supply-chain GSC can be integrated into identification process leveraging...
