Journal of High Energy Physics, 2022 Abstract We use holography to study collisions of phase domains formed in a four-dimensional, strongly-coupled gauge theory with a first-order, thermal phase transition. We find three qualitatively different dynamical regimes depending on the collision velocity.

The Physics Teacher, 2021 This paper addresses a popular topic in science teaching and competitions for primary and secondary school students. Experiments with colliding coins are relatively easy to perform and therefore popular in science lessons. We used the idea in the science competition we organized for pupils aged 6 to 13 years.

Physical Review E, 2018 We provide a theoretical framework to analyze the properties of frontal collisions of two growing interfaces considering different short range interactions between them. Due to their roughness, the collision events spread in time and form rough domain boundaries, which defines collision interfaces in time and space.

Collision Lesions: Genuine Collision (Conflict) or not?
Acta dermatovenerologica Croatica : ADC, 2022 By definition, the term "collision lesion" refers to two or more tumors coinciding in the same anatomic position or visceral organ. Collision lesions coexisting on the same skin location are defined as collision skin lesions (CSLs). Although this term implies a conflict between the tumors, this is not the case.

A Hybrid Collision Model for Safety Collision Control [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 Self-collision detection and avoidance are essential for reactive control, in particular for dynamics robots equipped with legs or arms. Yet, only few control methods are able to handle such constraints, and it is often necessary to rely on path planning to define a collision-free trajectory that the controller would then track.

Binomial collisions and near collisions
Integers : Electronic Journal of Combinatorial Number Theory, 2017 We describe efficient algorithms to search for cases in which binomial coefficients are equal or almost equal, give a conjecturally complete list of all cases where two binomial coefficients differ by 1, and give some identities for binomial coefficients that seem to be new.

Analysis and Treatment of Vibration Fault of a 1 050 MW Steam Turbine Generating Unit
Zhejiang dianli, 2022 During the capital construction commissioning of unit No.1 of a 2×1 050 MW coal-fired power plant， vibration of bearings No.5 and No.6 exceeded the set standard and become rather unstable， holding up the project.

A Class of Collisions of Plane Impulsive Light--Like Signals in General Relativity [PDF]
, 2002 We present a systematic study of collisions of homogeneous, plane--fronted, impulsive light--like signals which do not interact after head--on collision. For the head--on collision of two such signals, six real parameters are involved, three from each of

Extended Abstracts of the 2023 CHI Conference on Human Factors in Computing Systems, 2023 Collision, "the violent encounter of a moving body with another", is poorly understood in HCI. When we discuss people colliding with the physical artifacts we create, or colliding with each other while using our systems, this is primarily treated as a hazard, something which we should design to avoid.
