High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

Advanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

A Comparative Study of Multiple Deep Learning Algorithms for Efficient Localization of Bone Joints in the Upper Limbs of Human Body [PDF]

Advances in Intelligent Systems and Computing, vol 1439. Springer, Singapore (2023)
This paper addresses the medical imaging problem of joint detection in the upper limbs, viz. elbow, shoulder, wrist and finger joints. Localization of joints from X-Ray and Computerized Tomography (CT) scans is an essential step for the assessment of various bone-related medical conditions like Osteoarthritis, Rheumatoid Arthritis, and can even be used

Constructing Ion‐Bridging Structure with Controlled Cracks in Plasticized PVC with Graphene for Highly Sensitive Strain Sensor with a Wide Strain Range

Advanced Science, EarlyView.
A highly stretchable strain sensor is presented, that leverages controlled crack formation and ion bridging in a polyvinyl chloride gel/graphene to achieve exceptional sensitivity (gauge factor up to 1.5 × 10⁶) and mechanical stability. By optimizing plasticizer properties, the conductive pathways are finely tuned, enabling robust, real‐time monitoring

Multi-scale approach to invasion percolation of rock fracture networks [PDF]

Journal of Hydrology 519, 353 (2014), 2014
A multi-scale scheme for the invasion percolation of rock fracture networks with heterogeneous fracture aperture fields is proposed. Inside fractures, fluid transport is calculated on the finest scale and found to be localized in channels as a consequence of the aperture field. The channel network is characterized and reduced to a vectorized artificial
