A new hybrid finite element approach for three-dimensional elastic problems
Archives of Mechanics, 2012 A new fundamental solution based finite element method (HFS-FEM) is presented for analyzing three-dimensional (3D) elastic problems with body forces in this paper. It begins with deriving formulations of 3D HFS-FEM for elastic problems without body force

On a Periodic Solution of the 4-Body Problems
Advances in Mathematical Physics, 2014 We study the necessary and sufficient conditions on the masses for the periodic solution of planar 4-body problems, where three particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.

Development of a wind-tunnel for spinning body using magnetic suspension
Nihon Kikai Gakkai ronbunshu, 2017 A wind-tunnel system for spinning body has been proposed to measure hydrodynamic forces acting on the body. In the proposed system, the body is suspended and rotated by electromagnets. The forces are measured from the control signal for suspension.

Sex and Rural/Urban Centre Location as Determinants of Body Image Self-Perception in Preschoolers
Children, 2022 Body image and self-perception are highly related to psychological health and social well-being throughout the lifespan. Body image problems can lead to pathologies affecting the quality of life. Thus, it is essential to analyse perceived self-image from

$L^1$-optimality conditions for circular restricted three-body problems
, 2015 In this paper, the L1-minimization for the translational motion of a spacecraft in a circular restricted three-body problem (CRTBP) is considered. Necessary con- ditions are derived by using the Pontryagin Maximum Principle, revealing the existence of ...

Solvable Many-Body Models of Goldfish Type with One-, Two- and Three-Body Forces
Symmetry, Integrability and Geometry: Methods and Applications, 2013 The class of solvable many-body problems ''of goldfish type'' is extended by including (the additional presence of) three-body forces. The solvable N-body problems thereby identified are characterized by Newtonian equations of motion featuring 19 ...

Advantages of Fluoroscopy for Accidental Ingestion of Multiple Magnets
Case Reports in Pediatrics, 2023 Foreign body ingestion is one of the common problems among children. A three-year-old girl presented to the emergency department 2 h after ingesting three small disk-type neodymium magnets. She had no gastrointestinal symptoms.

Regions of prevalence in the coupled restricted three-body problems approximation
, 2012 This work concerns the role played by a couple of the planar circular restricted three-body problem in the approximation of the bicircular model. The comparison between the differential equations governing the dynamics leads to the definition of region ...

Leveraging Small-Scale Quantum Computers with Unitarily Downfolded Hamiltonians
PRX Quantum, 2023 In this work, we propose a quantum unitary downfolding formalism based on the driven similarity renormalization group (QDSRG) that may be combined with quantum algorithms for both noisy and fault-tolerant hardware.
