  Structure Property Correlation of Polymer Dielectrics Using Electrical Response Data

  By B Ram Priya, G Mohandass, C Sridhathan, R Arangasamy, R Tharwin Kumar, NMG Kumar

  Abstract: Polymer dielectrics are foundational to insulation, capacitors, embedded passives, and flexible electronics, where performance is governed by the frequency-dependent electrical response rather than a single dielectric constant. This study presents a spectroscopy-aware structure–property correlation framework that transforms dielectric response data into physically interpretable spectral fingerprints and learns mappings from polymer descriptors to these fingerprints for prediction and interpretation. Broadband spectra are standardized on a log-frequency grid and parameterized using relaxation-informed …

  Image-Based Evaluation of Implant Tissue Interface Integrity in Polymer Orthopaedic Devices

  By Sheeba Santhosh, S.A. Yuvaraj, Chengamma Chitteti, NMG Kumar, M. Ram Prasad Reddy

  Abstract: Polymer orthopedic implants offer radiolucency and mechanical compatibility with bone, but long-term success depends on maintaining a stable implant–tissue interface. Routine imaging is widely available for follow-up, yet interface integrity is commonly judged qualitatively, limiting early detection of fixation compromise and reducing comparability across devices and time points. This work presents an image-based methodology to quantify interface integrity by extracting interpretable interface descriptors from a standardized interface belt around the …
