SUMMARY:Lecture / Discussion:AIM Seminar:  The Median Filter Scheme for Mean Curvature Flow
DESCRIPTION:Abstract:  In this talk we introduce mean curvature flow with some of its applications. This motivates the need for approximation algorithms. One of these is the thresholding scheme by Merriman\, Bence and Osher. We analyze a generalization of this to level set mean curvature flow on manifolds with generalized kernels\, the median filter scheme. To be precise\, we motivate the scheme\, present an algorithm for it and show the convergence. In this context\, we introduce generalized solution concepts of mean curvature flow. The most important one for us is the viscosity solution. This is joint work with Tim Laux.\n\nContact:  Selim Esedoglu

SUMMARY:Lecture / Discussion:Alan J. Hunt Memorial Lecture-U-M Biomedical Engineering--NOTE LOCATION CHANGE to NCRC BUILDING 10 AUDITORIUM
DESCRIPTION:2025 Alan J. Hunt Memorial Lecture\n\nMeasuring the Health of the Brain: From Global Networks to Local Biomarkers\nAbstract:\nHow do we measure the health of the brain? Unlike blood pressure or cholesterol\, there is no single number that captures brain function. We are developing the Brain Entropy Index (BEI)\, a new measure that integrates thermodynamics\, statistical modeling\, and brain imaging to provide a global indicator of brain health. Using data from modalities such as EEG\, fMRI\, and MEG\, the BEI can reliably separate healthy from diseased brains\, offering promise as a universal screening tool.\n\nYet\, just as a blood test might flag “illness” without specifying the disease\, a global index cannot by itself identify the underlying condition. Neurological disorders are defined by distinct local network dynamics\, and it is these dynamics that can give rise to robust biomarkers. One example is EpiScalp\, a computational tool we developed to model local brain networks from scalp EEG. EpiScalp can differentiate true epilepsy from seizure-mimicking disorders and from healthy brains\, providing a disorder-specific biomarker.\n\nTogether\, these approaches demonstrate a two-tiered framework: global measures can screen for health versus disease\, while local network dynamics serve as biomarkers that refine diagnosis and define specific conditions. More broadly\, this talk will illustrate how concepts from systems & control theory\, physics\, and data science can converge to open new frontiers in neuroscience and medicine.\n \nBio:\nSridevi Sarma received a B.S. in Electrical Engineering from Cornell University\, and an M.S. and Ph.D. in Electrical Engineering and Computer Science from Massachusetts Institute of Technology (MIT). She was a Postdoctoral Fellow in the Brain and Cognitive Sciences Department at the MIT. Dr. Sarma is now a Professor in the Institute for Computational Medicine\, Department of Biomedical Engineering\, at Johns Hopkins University. Her research includes modeling\, estimation and control of neural systems using electrical stimulation to better diagnose and treat neurological disorders. She is PI for NeuroTech Harbor\, an NIH-funded BluePrint Hub for NeuroTechnologies and recently won an NIH Research Investigator Award (R35) that supports her translational research in epilepsy for 8 years.

SUMMARY:Conference / Symposium:Department Colloquium: Sarah Paul (NYU)
DESCRIPTION:\"Over-Efforting as Weakness of Will.\"  \n\nDetermination\, resoluteness\, tenacity\, perseverance\, and effort are paradigmatically viewed as marks of a strong will\, whereas giving up is often thought of as weakness – as giving in.  The central idea I will explore in this talk is that these familiar dynamics can also be inverted:  giving up can be hard\, and require strength of will\, while perseverance and continued effort can be a manifestation of weakness.  It is not uncommon to respond to adversity by doubling down and investing even more effort\, rather than by despairing and giving up.  I make a case that there is a general form of practical irrationality common to both succumbing to temptation and to the phenomenon of “over-efforting\,” such that it might be theoretically fruitful to embrace a conception of weakness of will that includes both phenomena.\n\nAbout Professor Paul:\nSarah Paul's research concerns agency and the philosophy of mind\, focusing on the nature of intention and belief. She is also interested in questions about self-knowledge\, self-control\, and what it means to believe in ourselves and others when it comes to difficult actions. She came to NYUAD from the University of Wisconsin-Madison and has also held visiting positions at M.I.T. and Bowdoin College. She is the author of an introductory textbook on the philosophy of action that was published by Routledge in 2021.

SUMMARY:Lecture / Discussion:HET Seminar | Quantum Null Ray: Effective dynamics and localized gauge invariant observables
DESCRIPTION:In this talk\, I'll review the construction of gravitational constraints and of the corresponding phase space along generalized Horizons.\n\nI will focus my expose on the study of the Raychauduri Constraint and its quantization\, which describes the dynamics of quantum null rays. I will present a detailed construction of the null Ray phase space and the localized gauge-invariant observables.\n\nSuch a construction requires the introduction of a preferred time frame called the dressing time\, which includes edge modes that allow localization along a null ray interval. Gauge-invariant observables are then obtained by dressing the fields with the dressing time.\n\nWe will see how the edge mode symplectic structure can be understood in terms of the integration of  degrees of freedom complementary to\n\nchosen region and how the gauge invariant observables include the covariant area element as a generator of reorientation of the frame. Overall the dressing time this provides a gravitational description of a quantum reference frame.\n\nFinally\, we will describe how the quantization procedure can be encoded through an effective deformation of the gravitational phase space labelled by a central charge.\n\nIf time permits\, I'll comment on the role the central charge plays in resolving the fundamental problem of time in quantum gravity and on some new results concerning the quantization of field theoretical reference frames.

SUMMARY:Workshop / Seminar:Navigating Academic Publishing as a Graduate Student
DESCRIPTION:The Comparative Studies in Society and History (CSSH) journal is pleased to invite you to an Informational Session on Academic Publishing in peer-reviewed journals on Friday\, November 7\, 2025\, from 3:00 - 4:30 p.m.\, in 411 West Hall. \n\nProfessor Jatin Dua (CSSH editor)\, Dr. David Akin (former CSSH managing editor for 25 years)\, and Professor Alyssa Paredes (recent CSSH author) will lead the session and share advice on how to successfully publish your research in academic journals in the humanities and social sciences. The session will introduce graduate students to the publication process from submission to acceptance\, and provide an overview of how to plan your journal article\, what gets published and why\, and common mistakes that get an article rejected. \n\nWe invite students to submit questions in advance about the publishing process\, and will also leave time for Q&A during the session. You may submit your questions through the Google form by November 6. \n\nAbout CSSH: \n\nComparative Studies in Society and History is an international forum for new research on problems of recurrent patterning and change in human societies through time and in the contemporary world. We feature the work of specialists in all branches of the social sciences and humanities\, bringing together multidisciplinary research\, cultural and area studies\, and innovative ventures in theory and method. We are committed to building connections and shared languages of comparison across the core fields of our readership: history\, anthropology\, political science\, and sociology. Along with articles and review essays\, CSSH publishes interviews with our contributors\, commentaries\, resources for teaching\, and discussions of emerging trends in the practice and politics of comparison.
