Physical parameters of a relativistic jet at very high redshift: the case of the blazar J1430+4204 [PDF]

open access: yes, 2010
Context. The high-redshift (z = 4.72) blazar J1430+4204 produced a major radio outburst in 2005. Such outbursts are usually associated with the emergence of a new component in the inner radio jet. Aims.

Secondary factor induced wind speed time-series prediction using self-adaptive interval type-2 fuzzy sets with error correction

open access: yesEnergy Reports, 2021
Accurate wind speed forecasting is very crucial for wind power generation systems, but the inherent randomness of wind speeds makes wind speed forecasting challenging. There have been many studies on predicting wind speeds, but they ignored the influence

Speeding up the HMC: QCD with Clover-Improved Wilson Fermions

open access: yes, 2002
We apply a recent proposal to speed up the Hybrid-Monte-Carlo simulation of systems with dynamical fermions to two flavor QCD with clover-improvement. For our smallest quark masses we see a speed-up of more than a factor of two compared with the standard

Vehicle speed as a factor of road traffic safety

open access: yesДороги і мости
Introduction. Road safety is one of the most pressing global challenges, particularly in Ukraine. Every year, millions of people worldwide are injured or lose their lives as a result of road traffic accidents (RTAs). These are not only personal tragedies

Characterization of Dynamic Friction Factor for FEM Modeling of High Speed Process

open access: yesEngineering Transactions, 2014
The present study aims to establish through a series of friction tests the trends of the dynamic factor according to sliding speed. A ballistic set-up using an air gun launch is used to measure the friction coefficient for the steel/carbide contact ...

New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]

open access: yes, 2014
For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase

Potential Early Risk Biomarkers for Reduced Forced Expiratory Volume in Children Post‐Hematopoietic Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

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 ...
