Four-nucleon force contribution to the binding energy of 4He

open access: yesEPJ Web of Conferences, 2010
We study the four-nucleon force contribution to the binding energy of 4He in the framework of chiral nuclear interactions. The four-nucleon forces start to contribute in the next-to-next-to-next-to leading order.

Analyzing false positives of four questions in the Force Concept Inventory

open access: yesPhysical Review Physics Education Research, 2018
In this study, we analyze the systematic error from false positives of the Force Concept Inventory (FCI). We compare the systematic errors of question 6 (Q.6), Q.7, and Q.16, for which clearly erroneous reasoning has been found, with Q.5, for which ...

Experimental assessment for non-monolithic slab-column connections

open access: yesAin Shams Engineering Journal, 2021
It is common practice to use non-monolithic connections to connect the new flat slabs to the existing columns for upgrading the stories number of the existing buildings, despite the lack of design guidelines for the non-monolithic connection.

Unification of the four forces in the Spin(11,1) geometric algebra

open access: yesPhysica Scripta, 2023
Abstract SO(10), or equivalently its covering group Spin(10), is a well-known promising grand unified group that contains the standard-model group. The spinors of the group Spin(N) of rotations in N spacetime dimensions are indexed by a bitcode with [N/2] bits. Fermions in Spin(10) are described by five bits yzrgb, consisting of two weak

Ideberg type III glenoid fractures are caused by indirect force: A report of four cases

open access: yesTrauma Case Reports, 2020
Ideberg type III glenoid fractures are relatively rare, and the mechanisms of injury and treatment strategies remain controversial. We reviewed the fracture patterns and final radiological findings in four cases.

Evaluation of the relative contribution of meteorological and oceanic forces to the drift of ice islands offshore Newfoundland

open access: yesJournal of Glaciology, 2020
On 29 April 2015, four beacons were deployed onto an ice island in the Strait of Belle Isle to record positional data. The ice island later broke up into many fragments, four of which were tracked by the beacons.
