2Early warning system for shallow landslides using rainfall threshold and slope stability analysis显示文摘A combined cluster and regression analysis were performed for the first time to identify rainfall threshold that triggers landslide events in Amboori, Kerala, India. Amboori is a tropical area that is highly vulnerable to landslides. The 2, 3, and 5-day antecedent rainfall data versus daily rainfall was clustered to identify a cluster of critical events that could potentially trigger landslides. Further, the cluster of critical events was utilized for regression analysis to develop the threshold equations. The 5-day antecedent(xvariable) vs. daily rainfall(y-variable) provided the best fit to the data with a threshold equation of y = 80.7-0.1981 x. The intercept of the equation indicates that if the 5-day antecedent rainfall is zero, the minimum daily rainfall needed to trigger the landslide in the Amboori region would be 80.7 mm. The negative coefficient of the antecedent rainfall indicates that when the cumulative antecedent rainfall increases, the amount of daily rainfall required to trigger monsoon landslide decreases. The coefficient value indicates that the contribution of the 5-day antecedent rainfall is~20% to the landslide trigger threshold. The slope stability analysis carried out for the area, using Probabilistic Infinite Slope Analysis Model(PISA-m), was utilized to identify the areas vulnerable to landslide in the region. The locations in the area where past landslides have occurred demonstrate lower Factors of Safety(FS) in the slope stability analysis. Thus, rainfall threshold analysis together with the FS values from slope stability can be suitable for developing a simple, cost-effective, and comprehensive early-warning system for shallow landslides in Amboori and similar regions.Shruti Naidu K.S.Sajinkumar Thomas Oommen V.J.Anuja Rinu A.Samuel C.Muraleedharan 2018Geoscience Frontiers2018,9,6:12
3Studies on thermoresponsive polymers:Phase behaviour,drug delivery and biomedical applications显示文摘The present review aims to highlight the applications of thermoresponsive polymers.Thermo-responsive polymers show a sharp change in properties upon a small or modest change in temperature.This behaviour can be utilized for the preparation of so-called‘smart’drug delivery systems,which mimic biological response behaviour to a certain extent.Such materials are used in the development of several applications,such as drug delivery systems,tissue engineering scaffolds and gene delivery.Advances in this field are particularly relevant to applications in the areas of regenerative medicine and drug delivery.This review addresses summary of the main applications of thermoresponsive polymers which are categorized based on their 3-dimensional structure;hydrogels,interpenetrating networks,micelles,films and particles.The physico-chemical behaviour underlying the phase transition is also discussed in brief.Arijit Gandhi Abhijit Paul Suma Oommen Sen Kalyan Kumar Sen 2015Asian Journal of Pharmaceutical Sciences2015,10,2:9

5Multi-parametric MR imaging of transition zone prostate cancer: Imaging features, detection and staging显示文摘Magnetic resonance (MR) imaging has been increasingly used in the evaluation of prostate cancer. As studies have suggested that the majority of cancers arise from the peripheral zone (PZ), MR imaging has focused on the PZ of the prostate gland thus far. However, a considerable number of cancers (up to 30%) originate in the transition zone (TZ), substantially contributing to morbidity and mortality. Therefore, research is needed on the TZ of the prostate gland. Recently, MR imaging and advanced MR techniques have been gaining acceptance in evaluation of the TZ. In this article, the MR imaging features of TZ prostate cancers, the role of MR imaging in TZ cancer detection and staging, and recent advanced MR techniques will be discussed in light of the literature.Arda Kayhan Jacob Oommen Aytekin Oto 2010World Journal of Radiology2010,2,5:3
6Magnetic resonance enterography in Crohn’s disease: Standard and advanced techniques显示文摘Crohn's disease (CD) is a chronic autoimmune disorder that affects mainly young people. The clinical management is based on the Crohn's Disease Activity Index and especially on biologic parameters with or without additional endoscopic and imaging procedures, such as barium and computed tomography examinations. Recently, magnetic resonance (MR) imaging has been a promising diagnostic radiologic technique with lack of ionizing radiation, enabling superior tissue contrast resolution due to new pulse-sequence developments. Therefore, MR enterography has the potential to become the modality of choice for imaging the small bowel in CD patients.Arda Kayhan Jacob Oommen Farid Dahi Aytekin Oto 2010World Journal of Radiology2010,2,4:3
7Total hip arthroplasty in fused hips with spine stiffness in ankylosing spondylitis显示文摘Ankylosing spondylitis(AS)is characterized by involvement of the spine and hip joints with progressive stiffness and loss of function.Functional impairment is significant,with spine and hip involvement,and is predominantly seen in the younger age group.Total hip arthroplasty(THA)for fused hips with stiff spines in AS results in considerable improvement of mobility and function.Spine stiffness associated with AS needs evaluation before THA.Preoperative assessment with lateral spine radiographs shows loss of lumbar lordosis.Spinopelvic mobility is reduced with change in sacral slope from sitting to standing less than 10 degrees conforming to the stiff pattern.Care should be taken to reduce acetabular component anteversion at THA in these fused hips,as the posterior pelvic tilt would increase the risk of posterior impingement and anterior dislocation.Fused hips require femoral neck osteotomy,true acetabular floor identification and restoration of the hip center with horizontal and vertical offset to achieve a good functional outcome.Cementless and cemented fixation have shown comparable long-term results with the choice dependent on bone stock at THA.Risks at THA in AS include intraoperative fractures,dislocation,heterotopic ossification,among others.There is significant improvement of functional scores and quality of life following THA in these deserving young individuals with fused hips and spine stiffness.Anil Thomas Oommen Triplicane Dwarakanathan Hariharan Viruthipadavil John Chandy Pradeep MathewPoonnoose Arun Shankar A Roncy Savio Kuruvilla Jozy Timothy 2021World Journal of Orthopedics2021,12,12:2

9Learning two-phase microstructure evolution using neural operators and autoencoder architectures显示文摘Phase-field modeling is an effective but computationally expensive method for capturing the mesoscale morphological and microstructure evolution in materials.Hence,fast and generalizable surrogate models are needed to alleviate the cost of computationally taxing processes such as in optimization and design of materials.The intrinsic discontinuous nature of the physical phenomena incurred by the presence of sharp phase boundaries makes the training of the surrogate model cumbersome.We develop a framework that integrates a convolutional autoencoder architecture with a deep neural operator(DeepONet)to learn the dynamic evolution of a two-phase mixture and accelerate time-to-solution in predicting the microstructure evolution.We utilize the convolutional autoencoder to provide a compact representation of the microstructure data in a low-dimensional latent space.After DeepONet is trained in the latent space,it can be used to replace the high-fidelity phase-field numerical solver in interpolation tasks or to accelerate the numerical solver in extrapolation tasks.Vivek Oommen Khemraj Shukla Somdatta Goswami Rémi Dingreville George Em Karniadakis 2022npj Computational Materials2022,,1:2
