| 11:00 - 12:00 Wednesday Weekly Seminar - google meet Project 8: The Quest for the Neutrino Mass Measurement Using Cyclotron Radiation Emission Spectroscopy School PARTICLES AND ACCELERATORS Abstract: Project 8 is a tritium beta-decay endpoint experiment which is planned to look for neutrino mass in the range allowed by the inverted neutrino mass hierarchy. The cyclotron radiation emission spectroscopy is the devised technique for a precise measurement of relativistic electrons energy. The technique was demonstrated to be operational utilizing mono-energetic conversion electrons from gaseous 83mKr in a small waveguide detector. In the most recent advance, the Project 8 collaboration measured a continuous spectrum by using tritium as the source of relativistic electrons. Here we present the hardware upgrades and overcome analysis ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Glycosylation promotes the cancer regulator EGFR-ErbB2 heterodimer formation — molecular dynamics study School PHYSICS Abstract: ErbB family of receptor tyrosine kinases play significant roles in cellular differentiation and proliferation. Mutation or overexpression of these receptors leads to several cancers in humans. The family has four homologous members including EGFR, ErbB2, ErbB3, and ErbB4. From which all except the ErbB2 bind to growth factors via the extracellular domain to send signals to the cell. However, dimerization of the ErbB receptor occurs in extracellular, transmembrane, and intracellular domains. The ErbB receptors are known to form homodimers and heterodimers in the active form. Heterodimerization increases the variety of identif ... 15:30 - 17:00 IPM Webinar - Brain controllability: mirage or reality? School COGNITIVE SCIENCES Description : A major goal of applied neuroscience is to understand how to achieve controlled perturbations of brain activity through stimulation or brain-computer interfaces. This aim is particularly appealing for medical applications, where one wishes to restore normal activity patterns in subjects affected by neurological or psychiatric disorders. In recent years, several authors have proposed to frame this problem within control theory, a well established engineering paradigm dealing with the control of dynamical systems. In this framework, a model of the autonomous (uncontrolled) dynamics of the system is used to ... 18:00 - 19:00 Physics Colloquium Einstein vs Einstein: The Great War School PHYSICS Within the span of seven months in the midst of the Great War, Albert Einstein published two seminal papers, on "Quantum Emission and Absorption" and "Field Equations of Gravitation", that laid the foundations of modern physics. Our century-long odyssey starts here, taking us through the rise of holography, fuzzballs, firewalls, quantum chaos, and gravitational wave astronomy. However, in the end, it will land us back within those fateful seven months, where Einstein's July 1916 "Strahlungs-Emission und -Absorption nach der Quantentheorie" may prove to be the ultimate undoing of his December 1915 "Die Feldgleichungen der Gravitation". I will ... |
