The Light We Give: Sikh Wisdom for Cultivating Empathy and Justice
No full textGrowing up in South Texas, Dr. Simran Jeet Singh and his brothers confronted racism daily. As a turbaned, bearded, brown-skinned Sikh, he continued to face prejudice and hate in college and beyond. Simran chose to be defined not by the negativity that often surrounded him but by the Sikh teachings of love and justice that he grew up with. Delving deep into these core tenets of Sikh wisdom, he has sought to embrace an outlook that guides us to see the good in everyone and to forge a path of positivity, connection, and service—a way of life that so many of us are seeking in today’s world.
We all say that we choose love over hate. But when tested, we realize that it’s easier said than done and that our empathy for others is not rooted deeply enough. As a turbaned and bearded Sikh man, Simran has been subjected to racism his whole life. He has been working on the frontlines of hate violence for more than a decade. And yet, he has managed to avoid falling into the toxic trap of hate and anger. In this lecture, drawing on his recent book The Light We Give, he will draw from his personal experiences and from hate incidents he has witnessed firsthand to share the wisdom he has gained on what it really takes to choose love over hate.
Simran Jeet Singh, Ph.D., is the Executive Director of the Religion & Society Program at the Aspen Institute and the author of the national bestseller The Light We Give: How Sikh Wisdom Can Transform Your Life (Riverhead, Penguin Random House). Simran\u27s thought leadership on bias, empathy, and justice extends across corporate, university, and government settings. He is an Atlantic Fellow for Racial Equity with Columbia University and the Nelson Mandela Foundation, a Soros Equality Fellow with the Open Society Foundations, a Visiting Lecturer at Union Seminary, and a Senior Advisor on Equity and Inclusion for YSC Consulting, part of Accenture.

Fluorescence Measurements of Phototrophic Sulfur Bacteria for Applications in Water Column Profiling
No full textUnlike plants that produce oxygen during photosynthesis, phototrophic sulfur bacteria use sulfide and sunlight to produce carbohydrates and elemental sulfur. These bacteria require a unique aquatic environment to thrive: one that is anoxic (depleted of oxygen) and rich in hydrogen sulfide. Such conditions are found in a number of stratified lakes around the world including several in Northern Indiana. Studying the ecology and geochemical conditions that promote habitable conditions for phototrophic bacteria in lakes provides insight into the Early Earth (thought to be anoxic), ocean anoxic events of the Mesozoic (70-250 million years ago) and modern low oxygen conditions of coastal environments such as the Dead Zone of the Gulf of Mexico. However, locating and directly sampling these bacterial populations in vast bodies of water is not an easy task. In this project, we investigate fluorescent properties of purple sulfur bacteria in order to develop a dependable sensor that can be deployed in the water column. We report a number of measurements of purple sulfur bacterium fluorescence in the near infrared region when excited at discrete wavelengths in the UV range. We use these bench-top measurements to design a water-proof apparatus equipped with an absorption and luminescent detector for localization of bacteria in lake water. This device will be deployed in anoxic lakes of Northern Indiana to find the in situ water column position of phototrophic bacteria

SUSY and DM searches in final states with two top quarks and missing transverse energy
No full textA search for SUSY and Dark Matter particles in association with two top quarks is presented. The supersymmetric partner of the top quark is searched for using a simplified SUSY model featuring stop pair production where each stop decays into a top quark and a neutralino, leading to a final state with two top quarks and missing transverse energy. The analysis strategy heavily uses machine learning techniques for event reconstruction and event discrimination, leading to significant improvements over previous analyses with the same dataset. In addition, simplified dark matter models are searched for where a new scalar or pseudoscalar mediator with Yukawa-like couplings is produced in association with two top quarks. This poster presents the latest ATLAS result using the full Run 2 dataset
Pixel Sensor Module Assembly Procedures for the CMS High Luminosity LHC Upgrade
No full textThe high luminosity phase of the LHC, poised to start taking data in 2027, aims to increase the instantaneous luminosity of the machine to 7.5 × 1034 cm−2 s −1. This will make it possible for experiments at CERN to make higher precision measurements on known physics phenomenon as well as to search for “new physics”. However, this motivates the need for hardware upgrades at the various experiments in order to ensure compatibility with the HL-LHC. This thesis describes some of the efforts to upgrade the inner-most layers of the Compact Muon Solenoid, namely the CMS silicon pixel tracking detector.Silicon sensors used to track particles are installed in the detector as part of a pixel sensor module. Modules consist of a silicon sensor-readout chip assembly that is wire-bonded to an HDI, or High Density Interconnects to provide power and signals. As part of the upgrade, 2,541 modules need to be assembled delicately and identically with alignment error margins as low as 10 microns. Assembly will be across three production sites in clean rooms to avoid dust and humidity contamination. In addition, the modules need to survive high magnetic fields and extended close-range radiation as part of the HL-LHC [1].In line with this effort, new materials and assembly procedures able to sustain such damage are investigated. Techniques to assemble modules are explored, specifically precision placing of parts with a robotic gantry and techniques to protect wirebonds. This is followed by a discussion of the accuracy and repeatability

No full textExploring new physics with top-quark pairs: a neural network approach using atlas run-2 data
No full textA novel search for particles beyond the standard model produced in association with top-quark pairs using the ATLAS Run-2 pp dataset at √s = 13 TeV is presented. Utilising events compatible with a semileptonic decay of top-quark pairs and large missing transverse energy, the study probes direct stop quark production, spin-0 mediators decaying into dark matter particles, and effective contact interactions between top quarks and neutrinos. An innovative and inclusive analysis approach based on neural networks is introduced, enabling sensitivity to a broad spectrum of new physics models without dedicated signal region optimisation. Significant improvements in sensitivity for stop-pair production and spin-0 mediators are achieved. No significant signs of new physics have been found, exclusion limits are thus set on parameters of the simplified models probed. Stop quarks up to 1080 GeV and neutralinos up to 600 GeV are excluded at a 95% confidence level. In searches for top quarks produced in association with dark matter particles, scalar (pseudoscalar) mediators with masses up to 250 (300) GeV are excluded at a 95% confidence level. The study also interprets the data within the framework of effective vector contact interactions between top quarks and neutrinos, setting lower limits on the new physics energy scale Λ between 2.12 TeV and 2.23 TeV
