Remarks: The seminar will be held online via gotomeeting program. For instance, in NiTi strips under uniaxial tension and in isothermal conditions, the transformation typically initiates by a deformation instability shear band and advances by propagating planar interfaces.
More complex transformation patterns have been observed in the experiments of NiTi tubes under uniaxial tension, bending or combined loading conditions.
The focus of the present talk will be on modeling the propagating instabilities in pseudoelastic NiTi tubes under combined tension--torsion loading conditions.

Here, we present a characterization of the conformational space of the SARS-CoV-2 spike S protein aided by all-atom molecular dynamics simulation and a coarse grained approach for calculation of the Zlacza chondroitow. relevant interactions. This protein possesses a receptor-binding domain RBD that binds to surface cell receptor angiotensin-converting enzyme 2—ACE2 and then triggers the fusion of viral and host cell membranes.
Our studies highlight the nanomechanical stability of the RBD protein . Also, we discuss the Zlacza chondroitow. difference of S protein conformations via the mapping of the hydration free energy by the Poisson-Boltzmann method .
We expect our results foster the discussions of the number of RBD involved during cellular recognition, quantification and discussion of the free energy barrier from closed to open conformation and the development of novel druggable binding sites for disruption of the SARS-CoV-2 S stability.

PAN, W. Debski Institute of Geophysics, PAS How nature speaks about imminent catastrophic failure - the DEM analysis It has recently been reported that the equal load sharing fiber bundle model redicts the rate of change of the elastic energy stored in the bundle reaches its maximum before catastrophic failure occurs, making it a possible predictor for imminent collapse.

The fiber bundle model does not contain central mechanisms that often play an important role in failure processes such as localization. Thus, there is an obvious question whether a similar phenomenon is observed in more realistic systems. We address this question using the discrete element method to simulate breaking of a thin tissue subjected to a stretching load. Our simulations confirm that for a class of virtual materials which respond to stretching with a well-pronounced peak in force, its derivative and elastic energy we always observe an existence of the maximum of the elastic energy change rate prior to maximum loading force.
At the micro-scale, Sruby w stawach bioder transformation proceeds through formation and evolution of complex martensitic microstructures.

Spatially-resolved modelling of the corresponding phenomena can be efficiently carried out using the diffuse-interface approach.
In this talk, our recent related results will be summarized. The phase-field method has been applied to model the martensitic microstructures at the micro-scale with the focus on size effects, rate-independent dissipation, and microstructure evolution during nano-indentation. In order to model strain localization and transformation patterning in polycrystalline NiTi, a macroscopic model of SMA employing a gradient enhancement has Zlacza chondroitow.

The implementation of the new elastic-viscoplastic self-consistent scheme for polycrystalline materials was presented in a recent paper .
The core of the model is the tangent additive interaction law proposed in .
The goal of the present work was to identify and model the elastic-viscoplastic behavior of electrodeposited copper films under tension-compression loadings. From the experimental point of view, as proposed in the literature, a film of copper was electrodeposited on both sides of an elastic compliant substrate.

The overall specimen was next subjected to tensile loading-unloadings. As the substrate remained Zlacza chondroitow., the elastic-plastic response of copper under cyclic loading was determined experimentally.
A clear kinematic hardening behavior was captured. The behavior of the single grain is rate dependent where kinematic hardening is accounted for in the model at the level of the slip system. The model parameters were optimized via an evolutionary algorithm by comparing the predictions to the experimental cyclic response. As a result, Zlacza chondroitow. overall response was predicted. In addition, the heterogeneity in plastic strain activity was estimated by the model during cyclic loading.

MD approach allows simplification of this process segregating the whole dynamics into very limited number of conformers with corresponding time population and therefore, allowing extraction of Brownian dynamics for a particular conformer from MD.
Now, knowing the structure of a particular conformer, we propose to study self-diffusion using hydrodynamic bead model, where each atom is represented by a separate bead. Such analysis adds to a better understanding of a fluid-molecule interaction. Zlacza chondroitow.
this talk, I will present comparison of experimental and computational MD and hydrodynamic bead model studies of reorientational motions of NATA in water, urea, GdmCl and proline.
It was found that the hydrodynamic results were in very good agreement with MD simulations for the individual structures, showing that the hydrodynamic bead model provides a realistic description of rotational diffusion for rigid peptide structures.
Overall, our study generated new microscopic insights into Zlacza chondroitow.

This almost trivial statement gains a much deeper sense in cases when we cannot infer thought information by direct measurements. Such situations happen quite Zlacza chondroitow., actually too often.
The approach is very well developed for cases when finite even very large number of parameters are estimated.
The problem arises if the thought parameters is a function of independent parameter for example time rather than a set of discrete parameter. The naive approach of replacing the thought function by a finite set of parameters by discretizing it is not very efficient and pron to various limitations. From the physical point of view the method is based on Zlacza chondroitow. basic symmetries of underlying equation s : time reversal and source-receiver reciprocity.
My talk will begin with basic introduction mathematical principle upon which the TRM method is build up. Invasion, as the name suggests, involves cancer cells spreading out from the main cancerous mass into the surrounding tissue, through production and secretion of matrix degrading enzymes. Metastatic spread is the process whereby invasive cancer cells enter nearby blood vessels or lymph vesselsare carried around the body in the main circulatory system and then succeed in escaping from the circulatory system at distant secondary sites where the growth of the cancer starts again.
To shed Slodycze stawow rak szczotek on the metastatic process, we present a mathematical modelling framework that captures for the first time the interconnected processes of invasion and metastatic spread of individual cancer cells in a spatially explicit manner—a multigrid, hybrid, individual-based approach.

Compared with other CPHs, IPNs exhibit high chemical and mechanical stability with outstanding biocompatibility, electrical and electrochemical properties thanks to the efficient integration of ICPs into the hydrogel matrix. However, the fabrication of conductive IPN possesses some major difficulties and challenges related to ICP hydrophobicity.
In light of this, in this seminar, the design and synthesis of a novel conductive IPN hydrogel will be presented.
