| 13:30 - 15:00 Weekly Seminar (Online) The imprint of the strong magnetic field on the gravitational waves of magnetars https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY In this research, the direct effect of the magnetic field on the gravitational wave emission is investigated. To do so, we study the energy-momentum tensor of a magnetic fluid in post-Newtonian (PN) theory. Using this tensor and examining the PN expansion of the gravitational potential of such fluid in the wave zone, it becomes clear that the magnetic field can play a role even in the first PN correction of the multipole moment tensor. This fact reveals the direct influence of the magnetic field on generating gravitational wave signals. As an application of this result, we investigate the direct effect of a super-strong magnetic field on the ... 14:00 - 16:00 IPM SCS Free Webinars Neural Engineering: Brain Control of Spinal cord stimulation for movement restoration following spinal cord injury School COGNITIVE SCIENCES IPM SCS Free Webinars Abstract: The restoration of hand functions is an important priority for people with cervical spinal cord injury (SCI) (Anderson et al, 2004). Spinal cord stimulation is a promising technique to provide natural and fatigue-resistance contraction in the paralyzed limbs (Capogrosso et al. 2016,and Bonizzato et al. 2018). These studies showed that controlling stimulation of the spinal cord with decoded commands from the cortical spike information can restore locomotion after SCI . The main goal of our study is to solve spike decoding chall ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Interacting active particles in confinement School PHYSICS Abstract: Active particles exhibit interesting behaviors near bounding surfaces. Their accumulation near boundaries arises from their persistent motion. Various properties of confined active systems, such as active ?ow patterns and stabilization of dense suspensions into spiral vortices have been experimentally observed. Inter-particle interactions play an important role in determining such intriguing behaviors. A simple model of alignment interaction first proposed by Vicsek et al. has been widely used to describe development of long-range orientational order and pattern formation in active systems. In this talk, I will first ... |
