Fundamental photon orbits in the double Schwarzschild space-time

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We consider photon orbits in the space-time consisting of two identical Schwarzschild black holes in static equilibrium. In particular, we focus on fundamental photon orbits – bound photon orbits that do not fall into either black hole or go to infinity.

The Effect of Teprotumumab on Eyelid Position in Patients with Thyroid Eye Disease

open access: yesPlastic and Reconstructive Surgery, Global Open, 2022
Summary:. Teprotumumab has been shown to improve proptosis and clinical activity scores (CAS) in patients with thyroid eye disease, but little has been published regarding its effects on eyelid retraction. The purpose of this work was to evaluate changes

A Systematic Review of Evidence on the Clinical Effectiveness of Surveillance Imaging in Children With Medulloblastoma and Ependymoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Ballistic Orbits and Front Speed Enhancement for ABC Flows

open access: yes, 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 ...

Cross Sensor Simulation of Tomographic SAR Stacks

open access: yesRemote Sensing, 2019
This paper presents an algorithm for simulating tomographic synthetic aperture radar (SAR) data based on another stack actually gathered by a real acquisition system. Through the procedure here proposed, the simulated system can be evaluated according to

Estimating the Fractional Cycle Biases for GPS Triple-Frequency Precise Point Positioning with Ambiguity Resolution Based on IGS Ultra-Rapid Predicted Orbits

open access: yesRemote Sensing, 2021
We investigate the estimation of the fractional cycle biases (FCBs) for GPS triple-frequency uncombined precise point positioning (PPP) with ambiguity resolution (AR) based on the IGS ultra-rapid predicted (IGU) orbits. The impact of the IGU orbit errors

Pathogenic Germline PALB2 and RAD50 Variants in Patients With Relapsed Ewing Sarcoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Approximately 10% of patients with Ewing sarcoma (EwS) have pathogenic germline variants. Here, we report two cases: first, a novel germline pathogenic variant in partner and localizer of BRCA2 (PALB2) in a patient with a late EwS relapse. Its impact on homologous recombination is demonstrated, and breast cancer risk is discussed.

Orbit classification in the Hill problem: I. The classical case

open access: yes, 2017
The case of the classical Hill problem is numerically investigated by performing a thorough and systematic classification of the initial conditions of the orbits.

Asymptotic analysis of displaced lunar orbits [PDF]

open access: yes, 2009
The design of spacecraft trajectories is a crucial task in space mission design. Solar sail technology appears as a promising form of advanced spacecraft propulsion which can enable exciting new space science mission concepts such as solar system ...
