Advances in brain mechanics
Philip Bayly, Washington University in St. Louis, United States
Increasing evidence confirms that mechanics plays a critical role for brain function and dysfunction. In recent years, computational mechanics has emerged as a powerful tool to study and predict the behavior of the human brain under both physiological and pathological conditions. Yet, important challenges remain unresolved, which has hindered realistic and reliable numerical predictions. Brain tissue is ultra-soft, biphasic, and highly heterogeneous. In addition, it continuously changes its microstructural composition and architecture, as well as its mechanical properties in close relation to evolving brain function. Living brain cells actively sense and respond to their mechanical environment, leading to sophisticated coupling effects. Considering these highly dynamic effects will be critical to refine existing brain models and achieve personalized simulations of brain injury, disease or surgical procedures.
This special session will cover recent advances in brain mechanics, including novel experimental and modeling approaches, computational solid and fluid mechanics, and data-driven modeling, targeted toward personalized simulations that will provide value to the clinical community.
Bioengineering in the fight against COVID-19
The coronavirus disease 2019 (COVID-19) pandemic has claimed the life of more than a million people worldwide and is an unprecedented burden to the global society and economy and to national health systems. Bioengineering efforts are ongoing to find cure, develop treatment technologies, invent rapid and cost-effective diagnostic tests and to protect healthcare workers and the general public from infection through improvement of personal protective equipment. The many complications of COVID-19 also require development of preventative technologies to protect patients from deterioration. This session will review these efforts from multiple angles.

Computational challenges in analyzing pediatric musculoskeletal medical imaging
Chairs: Antonis Stylianou, University of Missouri – Columbia, USA; Tinashe Mutsvangwa, University of Cape Town, South Africa
Pediatric medical imaging provides crucial diagnostic and decision-making support to healthcare professionals in the management of neuromusculoskeletal disorders. While medical image acquisition, analysis, and synthesis has made tremendous progress, it has hit roadblocks when applied to pediatric imaging due to inherent challenges presented by pediatric anatomy. These include, but are not limited to, the scarcity of imaging databases across pediatric populations, image registration problems due to the growing musculoskeletal structures, unavailability of bone density maps, preclusion of follow-up imaging due to concerns about ionizing radiation, and lack of cadaveric studies to correctly understand the anatomical structure and variation. In general, analysis in pediatric MSK imagining has not kept pace with technological advancements that tend to focus on adult structures.
The overall goal of this special session is to cover recent computational advances in medical image processing and synthesis that leverage emerging technologies in the fields of machine learning, artificial intelligence, data-driven statistical modeling, multi-body and finite-element modeling, musculoskeletal biomechanics, motion analysis, clinical sciences, and biostatistics.

Mathematical modelling and simulation of tumours
Chairs: José Antonio Sanz-Herrera, University of Seville, Spain; José María Benítez, Technical University of Madrid, Spain; Jacobo Ayensa, University of Zaragoza, Spain
Cancer is one of the main causes of death in western countries. There are several reasons which difficult the finding of an efficient treatment to defeat this disease. One of these reasons is the multifactorial, highly dynamic and nonlinear nature of the evolution and progression of tumours. On the other hand, novel mathematical tools and computer capabilities may add some light in the discovery of new tumour cells’ mechanisms as well as to simulate the time effect of a certain drug in malignant cells. This special session will cover recent advances on mathematical cancer biology including, although not restricted to, advanced simulation approaches, as well as new modeling strategies based on data science and artificial intelligence amongst others, with application to different types of tumours.

Necessity and importance of high-performance computing to address the scalability issue of biomedical-related computational studies
Chairs: Mojtaba Barzegari and Liesbet Geris, Department of Mechanical Engineering, KU Leuven, Leuven, Belgium
The use of computational modelling in medical-related studies has risen exponentially in recent years, and more reliable developed models are being released each year for various sub-fields of this domain. Several hurdles exist to accelerate the uptake of said models into clinical practice. Currently, much effort is put into establishing model credibility, through verification and validation, and regulatory context of the simulation predictions. Another hurdle, having received less attention thus far, is that of scalability of the developed codes and models to benefit from rapidly growing computing power and advancements in hardware resources. As demonstrated by a few international biomedical computational modelling and simulation-oriented initiatives like CompBioMed, similar to other fields, having scalable models that use the available computing resources more efficiently allows constructing of more comprehensive models that capture more realistic phenomena, leading to more accurate simulations and predictions. Taking advantage of high-performance computing (HPC) techniques can help the field to move towards more reliable and accurate computational models for personalized medicine.
Numerical models of mechanobiology

Numerical Models describing biological processes depending on mechanical signals are increasingly used in research. Some models are trying to describe the complex time dependent coupling of such biological processes with the non-constant behavior of smart or degradable implants. Some other models might even be close to jump to a clinical usage.

Tools for quantifying cell mechanics
Chairs: Hans Van Oosterwyck and Mar Condor, University of Leuven, Belgium
The importance of cell mechanics has long been recognized for cell fate and function. However, the analysis of how cells sense and respond to mechanical forces has been limited by the availability of techniques that can measure these forces in living cells while simultaneously measuring changes in cell and molecular activity. To confront this challenge new engineering methods combined with computational models have been developed in the last years to measure and manipulate the mechanical properties of cells as well as their internal cytoskeletal and nucleus.
In this session we will provide a space to present and discuss the latest advancements in the development of new tools for quantifying cell mechanics, including some of the most relevant ones such as traction force microscopy techniques.
