$L^1$-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.

Few-body decay and recombination in nuclear astrophysics [PDF]
, 2010 Three-body continuum problems are investigated for light nuclei of astrophysical relevance. We focus on three-body decays of resonances or recombination via resonances or the continuum background.

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.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

An efficient Generalized Geometry Contact algorithm including modal reduction flexible bodies
Mechanical Engineering Journal, 2017 In the MFBD (Multi-Flexible-Body Dynamics) (RecurDyn, 2017), the contact analysis is very important. To develop the general purpose contact algorithm for rigid and flexible bodies, the Generalized Geometry Contact algorithm, which is called ‘Geo Contact ...

A general T-matrix approach applied to two-body and three-body problems in cold atomic gases
, 2012 We propose a systematic T-matrix approach to solve few-body problems with s-wave contact interactions in ultracold atomic gases. The problem is generally reduced to a matrix equation expanded by a set of orthogonal molecular states, describing external ...
