Revisiting the Milky Way stellar long bar and the 3 kpc arm★
Astronomy & AstrophysicsContext. One of the most difficult and unexplored regions of the Milky Way is the highly extincted in-plane central region within the Galactic coordinates 10◦ ≲ |ℓ| ≲ 30◦, |b| ≲ 3◦, where we have the long-bar and 3 kpc arm with intermediate-age stellar ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Time Domain Infinite Impulse Response Filtering Approach for Simulation of Pulse Propagation in Optical Fiber with PMD [PDF]
, 2005 In this thesis, we have developed a full time domain approach for the simulation of pulse propagation in the optical fiber. Same as split-step method in frequency domain, this approach also treats the linear and nonlinear process alternately.

Explicit Solution of the Time Domain Volume Integral Equation Using a Stable Predictor-Corrector Scheme [PDF]
, 2012 An explicit marching-on-in-time (MOT) scheme for solving the time domain volume integral equation is presented. The proposed method achieves its stability by employing, at each time step, a corrector scheme, which updates/corrects fields computed by the ...
