    I'll talk about a new dichotomy between arithmetic groups of rank one and arithmetic groups of rank bigger than one. Namely, whereas the category of definable sets in free groups or surface groups is simple, the category of definable sets in many higher rank arithmetic groups is as bad as it gets---it is equivalent to the category of definable sets over the natural numbers. One consequence of this phenomenon is that if G is such a higher rank arithmetic group, then there is an axiom---a first order statement---that holds for G but doesn't hold for any other finitely generated group.

    Living cells regulate their volume using a diverse set of mechanisms, to maintain their structural and functional integrity. The most widely-used mechanism to control cell volume is active ion transport. Experiments on adhered cells surprisingly revealed that their volume is significantly reduced as their basal area is increased1. We have developed a physical theory2 which considers both electrostatics and cell activity to predict a generic relation for how adhered cells regulate their volume in response to changes in their area, in agreement with the observations. Those measurements also show that the nuclear volume scales with the cell volume. Recently, the Volk group3 using intact-organism imaging, discovered that changes in nuclear volume dramatically varies the spatial organization of chromatin (DNA and associated proteins); this may have important consequences for gene expression. A simple polymeric model4 that includes the competition of chromatin self-attraction and interactions with the nuclear membrane, predicts transitions in the chromatin organization relative to the nucleus from peripheral to central to conventional, as the nuclear volume is reduced, as measured in the experiments of the Volk group.

    Recent discoveries indicate that the genomes of mammalian neurons are enriched for unique epigenetic modifications, including exceptionally high levels of non-CG DNA methylation. In my seminar, I will present our studies defining how a distinctive DNA methylation landscape is established in neurons and exploring how this methylation is read out to control critical gene expression programs. I will discuss the role of gene expression and genome architecture in shaping genomic profiles of non-CG methylation and highlight emerging mechanistic insights into how non-CG methylation and the Rett syndrome protein, MeCP2, work together to control transcription. Finally, I will outline growing evidence that disruption of this regulatory pathway contributes to neurodevelopmental disorders.

    We will first describe some classical theory of the queer Lie superalgebras q(n), such as Clifford modules, (generic) character formula for the irreducible representations, and classification of the blocks of finite-dimensional representations. Then we will focus our attention to q(3) and provide an explicit description of the Ext-quivers of the blocks. A proof of a ``virtual'' BGG reciprocity for q(n), which then gives the radical filtrations of indecomposable projective objects for q(3), will be provided.

    During the last decade, seismic sensing with optical fibers has become a reality. By analyzing the effect of seismic deformation on the fiber’s optical response, state-of-the-art Distributed Acoustic Sensing (DAS) now offers a 1-meter sensor resolution for tens of kilometers of fiber. In other words, a single DAS system can record up to 40,000 data channels at once – two orders of magnitude more than the entire earthquake-monitoring seismic network in Israel.

    In this talk, I will first introduce the underlying operating principles of DAS acquisition. These measurements are very different from conventional seismic sensors and need to be analyzed accordingly. Subsequently, most of the talk will revolve around DAS applications in various scenarios.

    We utilize the ambient seismic field, recorded on a standard telecommunication fiber deployed around the Stanford campus, to analyze subsurface properties. The same fiber can also be used to measure changes in traffic patterns due to the COVID-19 lockdown. With downhole DAS arrays deployed in deep vertical wells, we can study previously undetected low-magnitude earthquakes. Finally, we utilize DAS data recorded inside an unconventional gas field to unveil reservoir properties with unprecedented resolution.

    The brain is rife with feedback connections within and between its regions, which almost inevitably should give rise to dynamic activity in the underlying neuronal populations. In the taste system of awake rats, neurons sequentially transition between activity states that correlate with taste perceptions such as identity, palatability, and novelty. In my talk I will present the current knowledge regarding taste information processing in the taste system and will add our recent description of sub-second novelty information transmission through a new circuit. Next, I will present unpublished data showing the dynamic changes in neuronal activity as taste memory is acquired and consolidated across 12 hours in behaving rats. Last, I will show how taste learning helps us investigating the early, pre-pathological, stages of Alzheimer’s disease.
