    "Emergent gauge symmetries – making symmetry as well as breaking it
    ⇒ link to meeting"
    Streszczenie:Local gauge symmetries determine the interactions of elementary particles with exchange of gauge bosons between fermions. For example, the photon in Quantum Electrodynamics, gluon exchange between quarks in Quantum Chromodynamics and W and Z bosons in weak interactions. Gravitation can also be regarded as a gauge theory associated with co-ordinate transformations. Where do these symmetries come from? Do they unify at very-high energies, or might they be emergent, “dissolvi ng” in the extreme ultraviolet? Emergent gauge symmetries are seen in quantum many-body systems associated with quantum phase transitions, e.g., in high temperature superconductors, spin-liquids, string-net condensation and the A-phase of low temperature Helium-3. Might the gauge symmetries of particle physics also be emergent? If yes, what is the universality class and critical dimension of the quantum phase transition?

    In this Colloquium we discuss the scenario of an emergent particle physics Standard Model. We argue that the cosmological constant scale, 0.002 eV, comes out suppressed by factor of the large scale of emergence and is of the same order as the size of light Majorana neutrino masses, which are expected from thinking about neutrino oscillations data to be in region typically about 0.005 eV.

    "Science in China and its perspectives, the insider's look
    ⇒ link to meeting"
    Streszczenie:In the last fifteen years, the Chinese science and technology sectors have undergone a transformation. Currently, Chinese companies and public institutions are among global leaders in key technologies such as electrified transportation, supercomputing and big data, artificial intelligence, space flight, molecular diagnostics, DNA sequencing etc. Such rapid transformation has been achieved with a mixture of cultural, governmental, financial and market factors. The combination of long term planning, consistent financial support, active recruitment of overseas Chinese talent combined with the local characteristics of east Asian societies allowed the Chinese Science and Technology sector to repeat and even exceed the successes of their Japanese and Korean counterparts. Meanwhile, the sheer size of the Chinese population and economy suggests its leading global role in the years to come. However, due to perception, distance, and communication barriers, the current status of Chinese Science and Technology sectors, its overall structure and characteristics are generally poorly understood in the West. This lecture provides a glimpse into the Chinese education, science and technology sectors and highlights some fields where valuable lessons could be learned.

    "Skyrmions, Topology and Instantons"
    Streszczenie:Skyrmions are solitons in three space dimensions, constructed from a nonlinear pion field. I will discuss their basic properties, including their topological stability, and show examples. Instantons are solitons in four space dimensions, constructed from an SU(2) gauge field. I will show how Skyrmions can be approximated in terms of exact instantons, and instantons can be approximated in terms of exact Skyrmions.

    "Investigation of microstress evolution in Mg-alloy and Al/SiCp composite using TOF neutron diffraction"
    Streszczenie:The evolutions of stresses in both phases of the Al/SiCp composite subjected to thermal cycling during in situ compression test were measured using Time of Flight (TOF) neutron diffraction. It was confirmed that inter-phase stresses in the studied composite can be caused by differences in the coefficient of thermal expansion [1] for the reinforcement and matrix, leading to a different variation of phase volumes during sample heating or cooling. The experimental study of elastic-plastic deformation was carried out in situ on a unique diffractometer EPSILON-MDS (JINR in Dubna, Russia) measuring interplanar spacings simultaneously in 9 orientations of scattering vector. For the first time, the performed analysis of experimental data allowed to study the evolution of full stress tensor in both phases of the composite. The EPSILON-MSD diffractometer allows us to develop an experimental methodology based on the so-called crystallite group method in order to determine the evolution of the stresses localized in polycrystalline grains having different crystallographic orientations [2,3]. The methodology was applied to textured Mg AZ-31 alloy during compression along rolling direction (RD) performed at room temperature and the components of stress tensor were determined directly from measured lattice strains corresponding to chosen orientations of crystallite lattice. To calculate the strain evolution in twins (arising during deformation) the initial values of dhkl-spacings were estimated on the basis of peaks positions measured in different detectors. The components of stress tensor were determined directly from measured lattice strains corresponding to chosen orientations of crystallite lattice.

    "Looking for Early Signs of Alzheimer's Disease in Driving Patterns"
    Streszczenie:Abstract: Driving among older adults is a critical and timely public health issue. Thirty-eight million licensed drivers are aged 65 years or older, and the number of older adults is growing rapidly. Motor vehicle crashes are a leading cause of injury and death in older adults. Driving fatalities of adults 55 years and older are higher compared to younger adults. Also, fatalities increase with older adult age, such that the risk of death in a crash for drivers 85 years or older is nine times greater than it is for drivers of 69 years or younger. Identifying who will be at most risk of driving decline and predicting when the decline will occur will inform early driving safety intervention trials for older adults. Alzheimer's disease (AD) is recognized as a major contributor to driving risks. This talk will cover the underlying associations between symptomatic as well as preclinical Alzheimer's Disease and driving. Our cross-sectional results show that cognitively normal persons with more abnormal AD biomarker values at baseline obtain worse scores on an on-road driving test, and our longitudinal analyses show that AD biomarkers predict time to a road test rating of Marginal or Fail. Our most recent results show that using machine learning we can distinguish cognitively normal older drivers with preclinical AD from those without preclinical AD, from their daily driving data collected using in-vehicle GPS devices.
