        "description":"Abstract:\nModern computing architectures increasingly rely on iterative solvers that employ reduced-precision computation and communication-reduction techniques to lower time-to-solution and improve scalability. However, eigensolvers in scientific simulations have struggled to exploit such approximations without compromising accuracy.  We present an eigensolver R-ChFSI, a residual-based reformulation of Chebyshev Filtered Subspace Iteration (ChFSI) provably tolerant to inexact matrix\u2013vector products. By expressing the Chebyshev recurrence in terms of residuals rather than eigenvector estimates, R-ChFSI naturally accommodates multiple sources of approximation, including reduced-precision arithmetic (FP32 and TF32) in the filtering step, lossy compression with compression ratios exceeding 4x for inter-process communication, and approximate inverses for generalized eigenproblems, while preserving eigensolver robustness. Large-scale experiments on GPU accelerators are conducted using finite-element discretized generalized eigenproblems arising in Kohn\u2013Sham density functional theory for quantum modeling of materials. The results demonstrate that R-ChFSI achieves eigen-residual norms orders of magnitude smaller than standard ChFSI under comparable inexactness, while delivering substantial performance gains. This work provides a practical pathway toward approximation-tolerant eigensolvers enabling accurate and scalable simulations on modern computing architectures.\n\nBio:\nPhani Motamarri is an Assistant Professor in the Department of Computational and Data Sciences at the Indian Institute of Science, Bengaluru, where he leads the MATRIX Lab. He is an alumnus of the University of Michigan\u2013Ann Arbor, where he earned his PhD in Mechanical Engineering.\nHis research lies at the intersection of computational mechanics, materials science, numerical analysis, and high-performance computing. His work focuses on developing mathematical techniques and hardware-aware algorithms for quantum modeling of materials, with applications to structural and functional materials and multiscale modeling methodologies. He is also interested in machine learning frameworks for accelerating materials discovery and quantum computing, particularly in the context of quantum-centric supercomputing.\n\nMotamarri\u2019s research contributions include advances in finite-element methods, numerical analysis, and large-scale scientific software development. He is one of the lead developers of DFT-FE, an open-source, massively parallel finite-element code for density functional theory calculations. He received the ACM Gordon Bell Prize in 2023 and was a finalist for the ACM Gordon Bell Prize in 2019.",

No prior experience with meditation is required. \r\n\r\n*What will you learn?*\r\n\r\nThe guided meditation practice involves three simple steps: relaxation, rejuvenation, and meditation.\r\n\r\nRelaxation brings your body to a calm, steady posture creating a stillness at the physical level, and prepares the mind for meditation. We follow this with a rejuvenation method to detox the mind to let go of stress and complex emotions, and will leave you feeling light and refreshed. Lastly, learning to meditate by being mindful of your heart will connect you with yourself by listening to your heart\u2019s voice. \r\n\r\n*Why Meditate?*\r\n\r\nWhile physical fitness keeps our bodies in shape, meditation is an exercise for the mind and mental wellness. In addition to the measurable benefits mentally and physically, many people benefit from an unquantifiable inner poise and harmony. \r\n\r\n*Please take Learn to Meditate session if you are new to the practice. These sessions are offered Monthly.* https:\/\/events.umich.edu\/event\/128708\r\n\r\n*Event Details*\r\n\r\nHeartfulness Guided Meditation \r\nFridays from 12-12:30 p.m. ET (except during university season days \/ holidays)\r\nJoin Via Zoom Meeting\r\nRegister to receive Passcode (see \u201cRelated links\u201d\r\n\r\n\r\nThis wellness program is coordinated by ITS Teaching & Learning and provided at no cost by heartfulness.org.",

In the age of bird\u2019s-eye views, which imagined a perspective on American cities and towns from high in the air, balloonists were the only people who actually had the opportunity to see what the growing nation looked like from above. As the nineteenth century progressed, ballooning became a lucrative (if dangerous) business, as crowds gathered to watch balloons launch, and to see aeronauts risk their lives high in the air. Over time, the image of the hot air balloon proliferated in American print culture, being used to sell goods ranging from thread to canned beef. We hope that this exhibit conveys some of the thrill that would have come from seeing people fly for the first time.\n\nOn view May 22-August 28, weekdays from 12-4 pm.",

        "description":"The University of Michigan Duderstadt Center Gallery presents \u201cYou Next\u201d, a duo exhibition by Thede Ambrose and Kate Donoghue, curated by Nathan Byrne.\n\nOpening: Friday, May 29th 6-9pm\nClosing: Sunday, June 28th 2-5pm\n\nArtifacts, Illusion, and the Speculative mediate the exchange between Thede Ambrose and Kate Donoghue\u2019s practices.\n\nReferencing both personal and found documentary and advertisement imagery, Donoghue investigates the vacuous and hauntingly banal underbelly of commercial aspirations, constructing paintings that collapse expectations of consumerism into innate and corrupted desires.\n\nAmbrose navigates mediated violence, spirituality, and the abject, manifesting in perverse articulations of belief and reality. Imagistic sculpture and installation are generated through an expansive material interest, and an extensive archive of found imagery.\n\n\u201cYou Next\u201d presents the collisions of these practices. Cautionary tales, dreams, and fantasies of objectification come to a head in this collaboration between the two artists.\n\nGallery Hours: Tuesday - Friday, Noon-6pm and Sunday Noon-6 pm",
