Cancellative Elements in Finite AG-groupoids

Journal of New Theory, 2020
An Abel-Grassmann's groupoid (briey AG-groupoid) is a groupoid Ssatisfying the left invertive law: (xy)z = (zy)x for all x, y, z \in S. In the present paper, wediscuss the left and right cancellative property of elements of the nite AG-groupoidS.

SIXTH DEGREE OF FREEDOM

International Journal for Computational Civil and Structural Engineering, 2020
The article describes new types of finite elements that allow you to take into account all six degrees of freedom of the shell. In order to compose the finite elements, the Allman functional with a rotational degree of freedom is used.

Aluminum Extrusion Simulation Using Finite Elements

Eng
The complexity of an extrusion die profile is determined by its geometry. Various metrics such as the complexity index, shape factor, and form factor are used to quantify how geometric intricacy affects production costs, die life, energy consumption ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
