KELT-10b: The First Transiting Exoplanet from the KELT-South Survey -- A Hot Sub-Jupiter Transiting a V = 10.7 Early G-Star [PDF]

open access: yes, 2016
We report the discovery of KELT-10b, the first transiting exoplanet discovered using the KELT-South telescope. KELT-10b is a highly inflated sub-Jupiter mass planet transiting a relatively bright $V = 10.7$ star (TYC 8378-64-1), with T$_{eff}$ = $5948 ...

Research of Dynamic Characteristic of RV Reducer based on Bond Graph Theory

open access: yesJixie chuandong, 2020
In view of the dynamic characteristic analysis of RV reducer is difficult problems. A simulation model of RV reducer is established based on the theory of power bond graph, the mathematical formula for transmission ratio of RV reducer is deduced, and the

Rotate Vector Reducer Fault Diagnosis Model Based on EEMD-MPA-KELM

open access: yesApplied Sciences, 2023
With the increase of service time, the rotation period of rotating machinery may become irregular, and the Ensemble Empirical Mode Decomposition (EEMD)can effectively reflect its periodic state.

Efficient Large-scale Trace Checking Using MapReduce

open access: yes, 2015
The problem of checking a logged event trace against a temporal logic specification arises in many practical cases. Unfortunately, known algorithms for an expressive logic like MTL (Metric Temporal Logic) do not scale with respect to two crucial ...

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
