Satellite Requirements for Observation of Close Proximity Celestial Bodies
Engineering Proceedings, 2022 Celestial bodies of our solar system remain as a major unexplored and unexploited reserve of natural resources available to humans. Furthermore, those constitute a valuable source of information about the origins and evolution of the solar system and an ...

Ballistic Orbits and Front Speed Enhancement for ABC Flows
, 2016 We study the two main types of trajectories of the ABC flow in the near-integrable regime: spiral orbits and edge orbits. The former are helical orbits which are perturbations of similar orbits that exist in the integrable regime, while the latter exist ...

Finding Cliques in Projective Space: A Method for Construction of Cyclic Grassmannian Codes
IEEE Access, 2020 In general, the construction of subspace codes or, in particular, cyclic Grassmannian codes in some projective space Pq(n) is highly mathematical and requires substantial computational power for the resulting searches.

Resonant periodic orbits in the exoplanetary systems
, 2013 The planetary dynamics of $4/3$, $3/2$, $5/2$, $3/1$ and $4/1$ mean motion resonances is studied by using the model of the general three body problem in a rotating frame and by determining families of periodic orbits for each resonance.

Orbital varices and orbital wall defects [PDF]
British Journal of Ophthalmology, 2004 Orbital varices are a vascular hamartoma typified by a plexus of low pressure, low flow, thin walled and distensible vessels that intermingle with the normal orbital vessels.1–4 If freely communicating with the orbital circulation, engorgement of varices can occur by increasing venous pressure through the Valsalva manoeuvre,5 bending posture,6 coughing

FEBS Letters, EarlyView.In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Exact, E=0, Solutions for General Power-Law Potentials. I. Classical Orbits [PDF]
, 1994 For zero energy, $E=0$, we derive exact, classical solutions for {\em all} power-law potentials, $V(r)=-\gamma/r^\nu$, with $\gamma>0$ and ...
