In-Situ Particle Acceleration in Extragalactic Radio Hot Spots: Observations Meet Expectations

open access: yes, 2003
We discuss, in terms of particle acceleration, the results from optical VLT observations of hot spots associated with radio galaxies. On the basis of observational and theoretical grounds, it is shown that: 1. relatively low radio-radio power hot spots

Detecting Stellar Spots by Gravitational Microlensing [PDF]

open access: yes, 1999
During microlensing events with a small impact parameter, the amplification of the source flux is sensitive to the surface brightness distribution of the source star.

Local Current Distribution and "Hot Spots" in the Integer Quantum Hall Regime

open access: yes, 2006
In a recent experiment, the local current distribution of a two-dimensional electron gas in the quantum Hall regime was probed by measuring the variation of the conductance due to local gating.

Photometry of two DQ white dwarfs - search for spots [PDF]

open access: yes, 2012
Aims. The intensity profiles of the C_2 Swan bands in cool DQ white dwarfs cannot be adequately fitted with models that otherwise succesfully reproduce spectral features of the molecule CH in these stars.

Measles—an ENT diagnosis?

open access: yesClinical Case Reports, 2023
Key Clinical Message Ear, Nose and Throat (ENT) should remain vigilant about the emergence of measles in non‐endemic countries. Clinical suspicion is crucial in identifying this disease, with Koplik's spots being a pathognomonic sign. Forming part of the

Interferometry of chemically peculiar stars: theoretical predictions vs. modern observing facilities

open access: yes, 2014
By means of numerical experiments we explore the application of interferometry to the detection and characterization of abundance spots in chemically peculiar (CP) stars using the brightest star eps~Uma as a case study.

Anti-ferrodistortive Nanodomains in PMN Relaxor [PDF]

open access: yes, 2003
Temperature dependent studies of the 1/2(hk0) superlattice reflections \alpha spots by synchrotron x-ray scattering measurements were performed in (PMN) and (PMN-xPT) with Ti doping ...

Pazopanib Combined With Vincristine and Irinotecan in Relapsed Wilms Tumor: Encouraging Outcomes in a Heavily Pretreated Pediatric Cohort

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...

Study on the Effect of Heat Treatment on Microstructures and High Temperature Mechanical Properties of Welding Spots of Hot Stamped Ultra-High Strength Steel Patchwork Blanks

open access: yesMetals, 2021
Insufficient strength of welding spots is a common problem in the hot stamping process of ultra-high strength steel patchwork blanks (UHSSP). In this paper, the welding spots of 22MnB5 boron steel with thicknesses of 1.2 and 1.5 mm were austenitized and ...

Personalizing the Pediatric Hematology/Oncology Fellowship: Adapting Training for the Next Generation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...
