Crustal deformation refers to changes in the shape and structure of the Earth's crust over time, primarily driven by tectonic forces. It can result in features like folding when rocks bend under compression, faulting along fractures where movement occurs, uplift forming mountains, and subsidence when crust sinks. Crustal deformation is crucial to understanding geology, geological features, and plate tectonics.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
2. • Crustal Deformation
• Crustal deformation refers to the changes in the shape and structure of the Earth's crust due to the application
of stress over time. This process is primarily driven by tectonic forces and can result in various geological
features and phenomena. Crustal deformation can manifest in several ways, including:
• 1. **Folding:** When rocks are subjected to compressional forces, they may fold, forming anticlines (upward
arches) and synclines (downward troughs). These folded rock layers are common in mountain ranges.
• 2. **Faulting:** Faults are fractures in the Earth's crust along which movement has occurred. They can be
caused by horizontal compression (reverse fault), horizontal extension (normal fault), or horizontal shear
(strike-slip fault).
• 3. **Uplift:** Crustal deformation can lead to the uplift of land, resulting in the formation of mountain ranges
and plateaus. This uplift occurs when tectonic plates collide, pushing the crust upwards.
• 4. **Subsidence:** Conversely, crustal deformation can also cause subsidence, where the Earth's crust sinks or
settles due to various factors, such as the cooling and contracting of the Earth's interior.
• 5. **Isostasy:** Isostatic rebound is a form of crustal deformation that occurs when the Earth's crust adjusts its
elevation in response to changes in the distribution of weight on its surface. For example, after a glacier melts,
the land that was previously depressed by the weight of the ice may gradually rise back to its original position.
• Crustal deformation is a fundamental process in the field of geology and is crucial for understanding the Earth's
dynamic nature, the formation of geological features, and the study of earthquakes and plate tectonics.
3. Mountain Building
• Mountain building, also known as orogenesis, is a geological process that leads to the formation of mountain ranges. It is primarily
driven by the movement and interaction of Earth's tectonic plates. Here are the key processes involved in mountain building:
• 1. **Tectonic Plate Collision:** The most common scenario for mountain building occurs when two tectonic plates converge or
collide. There are several types of plate boundaries where this can happen, including convergent plate boundaries, where plates
move towards each other.
• 2. **Compression:** As tectonic plates collide, immense pressure and stress are generated. This compression of the Earth's crust
can cause rocks to fold, fault, and fracture.
• 3. **Folding:** Rocks in the crust can fold under the intense pressure, forming anticlines (upward-arching folds) and synclines
(downward-arching folds). These folded rock layers are characteristic of mountain ranges.
• 4. **Faulting:** Along with folding, faulting is common in mountain-building regions. Faults are fractures in the Earth's crust along
which movement occurs. Reverse faults, where rocks are pushed upward, are typical in compressional mountain-building zones.
• 5. **Uplift:** The intense compressional forces can lead to the uplift of large blocks of the Earth's crust. This uplift is what
ultimately results in the formation of mountains. Over millions of years, mountains can rise to great heights.
• 6. **Erosion:** While mountain-building processes create mountains, erosion continually wears them down. This includes
processes like weathering, sediment transport, and glacial activity. The balance between uplift and erosion determines the height
and longevity of mountain ranges.
• Mountain ranges are diverse and can vary greatly in terms of their age, height, and geological characteristics. Some famous
examples of mountain ranges formed through the process of mountain building include the Himalayas, the Rocky Mountains, and
the Andes. These geological features play a crucial role in shaping landscapes, climate patterns, and ecosystems on Earth.
