Optical microfiber loop resonator for gas pressure sensing

Physics Open, 2022
Based on theoretical modeling of optical microfiber loop resonator (MLR) and Hauf-Grigull relation, we have combined the ability of MLR in the sensing of ambient refractive index to the linear dependence of the refractive index of gases to the pressure ...

Characterization of Long-period Grating Refractive Index Sensors and Their Applications

Sensors, 2009
The influence of grating length and bend radius of long-period gratings (LPGs) on refractive index sensing was examined. Sensitivity to refractive indexes smaller than that of silica could be enhanced by bending LPGs.

Fiber semi-film SPR curvature sensor with the function of directional recognition

Results in Optics, 2020
We propose and demonstrate a fiber surface plasmon resonance (SPR) curvature sensor with the function of directional recognition by coating a metal film on one side of the fiber.

Structural Design of Ocean Temperature and Depth Sensor with Quick Response and High Sensitivity

Sensors, 2022
The electrical sensing elements used in the traditional XBT (Expendable Bathythermograph) have problems such as low sensitivity and slow response time, and it is difficult to overcome the complex marine environment using the time–depth formula.

Mutual Support by Sensor-Attacker Team for a Passive Target

IEEE Open Journal of Control Systems
We introduce a pursuit game played between a team of a sensor and an attacker and a mobile target in the unbounded Euclidean plane. The target is faster than the sensor, but slower than the attacker.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Plasmonic nanohelix-based 3D metasurfaces for refractive index sensing applications: A numerical parameter study

Results in Materials
We conducted a numerical study of a metasurface consisting of a core-shell SiO2@Au plasmonic helix array to analyze how variations in its geometrical parameters affect its sensitivity to changes in the refractive index of the surrounding environment ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
