Modeling contacts in a physically based simulation

open access: yesProceedings on the second ACM symposium on Solid modeling and applications - SMA '93, 1993
Abstract The paper presents a model of polyhedral contact that can be used in a physically based simulation. The model is based on a geometric analysis formulated as a static problem in 3D space. The geometric analysis of contact between a pair of objects determines the set of surface areas which are in contact and their associated normals.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Models for Contact Binaries [PDF]

open access: yesInternational Astronomical Union Colloquium, 1971
The well-known problem one has in constructing zero age contact binaries stems from the fact that given two mass values, the ratio of the radii for zero age stellar models differs from that derived from the Roche model (KUIPER 1941). Therefore one cannot achieve contact by adjusting just the distance of the two stars, since if for instance the distance

Mouse Model of Irritant Contact Dermatitis

open access: yesIranian Journal of Pharmaceutical Research, 2022
Background: Irritant contact dermatitis is a common inflammatory skin disease characterized by skin barrier dysfunction, eczematous dermatitis, and chronic itching. This disease severely affects the quality of life. Considering that the current treatment approaches are not ideal, more extensive research is needed to develop new treatments.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Multibody Model with Foot-Deformation Approach for Estimating Ground Reaction Forces and Moments and Joint Torques during Level Walking through Optical Motion Capture without Optimization Techniques

open access: yesSensors
The biomechanical-model-based approach with a contact model offers advantages in estimating ground reaction forces (GRFs) and ground reaction moments (GRMs), as it does not rely on the need for training data and gait assumptions.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Finite element study of displacement controlled fretting in cylinder contact with different axis crossing angles

open access: yesAdvances in Mechanical Engineering, 2022
There is inevitably an angular offset during contact of mechanical structures such as roller bearings or gears. Most of the previous contact models involve the contact between two parallel cylinders.

Contact Adaption during Epidemics: A Multilayer Network Formulation Approach

open access: yes, 2018
People change their physical contacts as a preventive response to infectious disease propagations. Yet, only a few mathematical models consider the coupled dynamics of the disease propagation and the contact adaptation process.
