SUMMARY:[Biophysics seminar] Simon Čopar: "Hyperuniformity and spherical structure factor"
DESCRIPTION:Hyperuniformity is an interesting measure of order which detects and quantifies long range positional correlations without requiring local crystalline order. This measure can be defined in real space\, through scaling of fluctuations of the number of building blocks in asymptotically large volumes\, or in frequency space\, where hyperuniformity manifests as a gap in the structure factor. \nI will review the hyperuniformity concepts and highlight the main obstacles and solutions that arise when dealing with a spherical geometry. I will present it on a few model spherical lattices.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Mauricio Comas-García: "Understanding selective packaging in Alphaviruses"
DESCRIPTION:Alphaviruses are a genus of positive-sense single-stranded RNA viruses that infect mammals and are transmitted by mosquitos. These viruses can cause a wide range of diseases\, from dengue-like symptoms (e.g.\, Chikungunya virus) to encephalitis (e.g.\, Venezuelan Equine Encephalitis virus). While during the ’80 and ’90s\, there was a great deal of interest in studying these viruses\, with time\, other pathogens became more attractive for research purposes. However\, the spread of the Chikungunya virus during the beginning of the XXI century to Asia\, Oceania\, and the Americas has brought new attention to these viruses. \nThese viruses have been widely studied from several aspects; structural biology\, epidemiology\, and immunology. For example\, we know the 3D structure of most of these viruses with almost an atomic detail. Furthermore\, a series of in vitro assembly experiments have shed light on some of the key RNA-protein interactions that are needed for core-like-practice assembly. Nonetheless\, there is very little information on how these viruses select their genome during infection. \nOur group has been working on creating a series of plasmids for expression in mammalian cells that contain a series of viral elements from the Chikungunya virus. The goal of these constructs is to generate a system that allows us to carry out competition experiments between mutant and wild-type viral RNAs in infected cells to find the packaging signal in the genomic RNAs that allows for its selective packaging. In this seminar\, we will present some preliminary results and the strategy we are following to understand how RNA structure and sequence determine selective packaging in an infected cell.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Gregor Posnjak: "From DNA origami to photonic crystals"
DESCRIPTION:The idea of using the predictable base pairing of DNA nucleobases for programmable assembly on the nanoscale dates back to the 1980s when the recently deceased Ned Seeman had the idea of using it to crystalize proteins on a DNA-based lattice for their structure determination with x-ray crystallography. After the first successful DNA nanostructures in the 1990s\, the real boom came after 2006 when the concept of DNA origami was introduced. The use of a long DNA scaffold strand in combination with short staple strands eliminated many of the short-comings of the earlier approaches and enabled robust programmable assembly with resolution on the order of nanometers. \nIn the first part of the talk I will introduce the concept of DNA origami and give a short review of the various structures and super-structures that were developed and their applications in drug delivery\, biophysics\, super-resolution microscopy\, sensing and plasmonics. In the second part I will shortly introduce photonic crystals as motivation for my work and then present a DNA-origami based self-assembled diamond lattice\, which we will use as a template for realization of visible spectrum photonic crystals.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Jaffar Hasnain: "Spontaneous emulsification induced by nanoparticle surfactants"
DESCRIPTION:Microemulsions\, mixtures of oil\, water\, and surfactant\, are thermodynamically stable. Unlike conventional emulsions\, microemulsions form spontaneously\, have a monodisperse droplet size that can be controlled by adjusting the surfactant concentration\, and do not degrade with time. To make microemulsions\, a judicious choice of surfactant molecules must be made\, which significantly limits their potential use. Nanoparticle surfactants\, on the other hand\, are a promising alternative because the surface chemistry needed to make them bind to a liquid-liquid interface is both well flexible and understood. Here\, we derive a thermodynamic model predicting the conditions in which nanoparticle surfactants drive spontaneous emulsification that agrees quantitatively with experiments using Noria nanoparticles. This new class of microemulsions inherits the mechanical\, chemical\, and optical properties of the nanoparticles used to form them\, leading to novel applications.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Tomer Stern: "Deconstructing Gastrulation at Single-Cell Resolution"
DESCRIPTION:Gastrulation movements in all animal embryos start with regulated deformations of patterned epithelial sheets. Current studies of gastrulation use a wide range of model organisms and emphasize either large-scale tissue processes or dynamics of individual cells and cell groups. In this work I take a step towards bridging these complementary strategies and deconstruct early stages of gastrulation in the entire Drosophila embryo\, where transcriptional patterns in the blastoderm give rise to region-specific cell behaviors. This approach relies on an integrated computational framework for cell segmentation and tracking and on efficient algorithms for event detection. Our results reveal how thousands of cell shape changes\, divisions\, and intercalations drive large-scale deformations of the patterned blastoderm\, setting the stage for systems-level dissection of a pivotal step in animal development.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Toshikaze Chiba: "Deformation and rearrangement of membranes in adhering vesicles"
DESCRIPTION:Vesicle is a molecular assembly configuring lipid bilayer shell\, and investigated as a model system of biological cell. Using both experimental observation and minimising the total energy\, we study the morphology of lipid vesicle doublet and triplet. We demonstrate that non-uniform tension in contact and non-contact zone can control a variety of different shape\, which is reminiscent of the four-cell stage in embryogenesis. Our results can be extended to the multiple adhering vesicles\, we briefly introduce our recent work in microfluidics experiment as a next step.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Clement Zankoc: "Active Instability and Nonlinear Dynamics of Cell-Cell Junctions"
DESCRIPTION:Active cell-junction remodeling is important for tissue morphogenesis\, yet its underlying physics is not understood. We study a mechanical model that describes junctions as dynamic active force dipoles. Their instability can trigger cell intercalations by a critical collapse. Nonlinearities in tissue’s elastic response can stabilize the collapse either by a limit cycle or condensation of junction lengths at cusps of the energy landscape. Furthermore\, active junction networks undergo collective instability to drive active in-plane ordering or develop a limit cycle of collective oscillations\, which extends over regions of the energy landscape corresponding to distinct network topologies.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Tanmoy Sarkar: "A minimal lattice model of lipid membranes with liquid-ordered domains"
DESCRIPTION:Binary or ternary mixtures of lipids and cholesterol featuring liquid-ordered (Lo) domains serve as model systems for studying the formation of lipid rafts in complex biological membranes. In the talk\, I will present a new lattice model of a binary mixture of saturated DPPC lipids and cholesterol\, which is the simplest model system exhibiting Lo domains in the sea of liquid-disordered (Ld) matrix. Simulations of mixtures of thousands of lipids and cholesterol molecules on time scales of hundreds of microseconds reveal a phase diagram that is in complete agreement with the well-established phase diagram of this mixture. The simulations provide important information on the morphologies and lifetime of the Lo domains which are not available by more detailed computational approaches. Strikingly\, the lattice simulation also reproduces local structures that have been observed in atomistic simulations. Specifically\, we find that the Lo domains are highly heterogeneous and consist of gel-like hexagonally packed clusters of ordered DPPC chains\, surrounded by cholesterol-rich regions at the domain boundaries.  The simulation results are explained by a new thermodynamic mechanism that considers the disparity between the packing interactions of ordered lipid chains with cholesterol and each other.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Matej Kanduč: "Lipids’ dilemma: a monolayer or a bilayer?"
DESCRIPTION:Lipids are amphiphilic molecules and tend to self-assemble into various supramolecular formations. The most eminent among them is the lipid bilayer – also a continuous barrier around all cells. Some surfaces have the ability to unfold the bilayer and “coat” themselves with a single layer of lipids – the monolayer. In the talk\, I will discuss what kinds of surfaces can do this. Lipid coatings are namely of viable importance in many biomedical applications owing to their biocompatibility.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Fabio Staniscia: "Surfactant-induced apparent line tension"
DESCRIPTION:Line tension is the tension generated at the three-phase contact line by the interaction between the phases\, and is usually negligible at large sizes while becoming important at smaller scales. In this talk I will introduce the concept and show how the addition of a surfactant in water can have the effect of generating an effective line tension. I will discuss its effects on the properties of the system\, as for instance on the contact angle of droplets on a substrate.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:[Biophysics seminar] Julija Zavadlav: "Neural network potentials trained top-down"
DESCRIPTION:Molecular modeling has become a cornerstone of many disciplines\, including soft matter physics. However\, the quality of predictions critically depends on the employed model that defines particle interactions. A class of models with tremendous success in recent years are neural network (NN) potentials due to their flexibility and capacity of learning many-body interactions. Traditionally\, these models are trained bottom-up on quantum mechanical data. Top-down approaches that learn NN potentials directly from experimental data have received less attention\, typically facing numerical and computational challenges when backpropagating through molecular dynamics (MD) simulations. We recently developed the Differentiable Trajectory Reweighting (DiffTRe) method\, which bypasses differentiation through the MD simulation for time-independent observables. Leveraging thermodynamic perturbation theory\, we avoid exploding gradients and achieve around 2 orders of magnitude speed-up in gradient computation for top-down learning. The effectiveness of DiffTRe is showcased on atomistic and coarse-grained models using diverse experimental observables including thermodynamic\, structural\, and mechanical properties. Our approach opens the way to high fidelity molecular models\, particularly when bottom-up data is unavailable or insufficiently accurate.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

DESCRIPTION:I will describe the basic molecular processes associated with disruption of homeostasis in a nerve cell and leading to neurodegeneration. We are mainly engaged in research into the causes of amyotrophic lateral sclerosis and frontotemporal dementia. We look at the mechanisms associated with mutations and with the altered behavior of certain genes\, RNAs\, and proteins. In particular\, we study the interactions of these molecules\, and their roles in processes such as nuclear transport\, cellular stress response\, and liquid-liquid phase separations characteristic of the formation of nonmembrane organelles.\n\n\nThe meeting will take place in the physics seminar room (106) in the main building.\n\n\n\n

SUMMARY:[Biophysics seminar] Andraž Gnidovec: "Simulating the packing of spherical ellipses"
DESCRIPTION:Packing problems are abundant in nature and are thoroughly researched both experimentally and in numerical models. In particular\, packings of anisotropic\, elliptical particles emerge in models of liquid crystals\, colloids\, as well as granular and jammed matter. While most of these studies deal with packings in Euclidean geometries\, there are many experimental systems where anisotropically shaped particles are confined to a curved surface\, such systems of colloidal rods trapped at the interface of emulsion droplets\, and protein adsorbates on vesicles. \nIn this talk\, I will first present an algorithm we developed to determine overlaps between two spherical ellipses. More generally\, the proposed method allows us to define a continuous contact function that could also be applied to long-range interactions\, however\, the use case as a distance metric must be considered with care. Returning to the main objective of the algorithm\, I will demonstrate its efficiency in packing simulations. I will show the random close packing results for a monodispersed system of hard ellipses and present some challenges in the analysis of the configurations in comparison to the ellipse packings in Euclidean space.\n\n\nThe talk will be in the tea room at the F1 department. It will be simultaneously transmitted online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio\n\n\n\n

SUMMARY:[Biophysics seminar] Antonio Šiber: "Mechanics of inactive swelling and bursting of porate pollen grains"
DESCRIPTION:The structure of pollen grains\, which is typically characterized by soft apertures in an otherwise stiff exine shell\, guides their response to changes in the humidity of the environment. These changes can lead to the desiccation of the grain and its infolding but also to excessive swelling of the grain and even its bursting. Here\, we use an elastic model to explore the mechanics of pollen grain swelling and the role that soft\, circular apertures (pores) play in this process. Small\, circular apertures typically occur in airborne and allergenic pollen grains so that the bursting of such grains is important in the context of human health. We identify and quantify a mechanical weakness of the pores\, which are prone to a rapid inflation once the grain swells to a critical extent. The inflation occurs as a sudden transition and may induce the bursting of the grain and the release of its content. This process crucially depends on the size of the pores and their softness. Our results provide insight in the inactive part of the mechanical response of pollen grains to hydration once they land on a stigma as well as on bursting of airborne pollen grains during changes in air humidity.\n\n\nThe meeting will take place online via Zoom: \nMeeting ID: 833 0750 1179 \nPasscode: bio

SUMMARY:Shaikh Saad: New Physics Solutions to Lepton Anomalous Magnetic Moments
DESCRIPTION:Recent precise measurement of the electron anomalous magnetic moment (AMM) adds to the longstanding tension of the muon AMM and together strongly point towards physics beyond the Standard Model. In this talk\, I present an overview of simultaneous solutions to lepton AMMs; both possibilities of new physics states appearing below and above the electroweak scale are discussed.\nhttps://indico.ijs.si/event/1295/

SUMMARY:[HEP seminar] Nudžeim Selimović: Lepton-Quark Fusion at Hadron Colliders\, precisely
DESCRIPTION:The collider phenomenology of TeV-scale leptoquarks had a new twist recently. The precise extraction of lepton parton distribution functions based on the LUX method facilitated an additional leptoquark production mechanism\, the resonant leptoquark production. After briefly reviewing and comparing different production mechanisms\, I will present the first computation of next-to-leading order QCD and QED corrections to the resonant leptoquark production cross-section at the Large Hadron Collider. Various NLO K-factors\, together with the theoretical uncertainties due to the renormalisation and factorisation scale variations and the limited knowledge of parton distribution functions will be shown.  I will conclude with a discussion of the possibility to disentangle the flavor structure of leptoquark interactions by exploiting the interplay between different production channels. \nJoin at: https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09

SUMMARY:[HEP Seminar] Florian Goertz: Dark Matter and Baryogenesis with an Inert Doublet
DESCRIPTION:In this talk\, we discuss the prospects to realize Dark Matter (DM) in the Inert Doublet Model\, while simultaneously enhancing the Electroweak Phase Transition (EWPhT) such as to induce electroweak baryogenesis. To this end\, we analyze the nature of the EWPhT in both light and heavy DM regions\, and explore a viable region where a non-trivial two-step EWPhT can appear\, allowing for the correct relic abundance and agreement with direct-detection bounds. Finally\, we discuss a new region for light DM with a small mass splitting\, lifting the usual assumption of exact degeneracy of the new non-DM scalars\, and comment on possibilities to implement enough CP violation to fulfill the Sakharov Conditions.
