Reference Values for Chronotropic Index from 1280 Incremental Cycle Ergometry Tests

Medicine & Science in Sports & Exercise, 2020
Supplemental digital content is available in the text. ABSTRACT Purpose Clinical cardiopulmonary exercise testing can determine causes of exercise limitation. The slope of heart rate (fC) versus oxygen uptake (V˙O2), which we call the chronotropic index (

The Transformation of Private Space in the Later Middle Ages: Rooms and Living Standards in the Kingdom of Valencia (1280-1450)

Journal of Urban History, 2020
This article undertakes a quantitative and qualitative analysis of probate inventories from a selection of towns and highly urbanized areas from the kingdom of Valencia in the period 1280-1460, which are used to explore the inner distribution of more ...

Fabrication of 12 µm pixel-pitch 1280 × 1024 extended short wavelength infrared focal plane array using heterojunction type-II superlattice-based photodetectors

Semiconductor Science and Technology, 2019
We present an intial demonstration of a 1280 × 1024 extended short-wavelength infrared focal plane array (FPA) imager with 12 μm pixel-pitch based on type–II InAs/AlSb/GaSb superlattice heterojunction photodetectors, with a novel bandstructure-engineered

I2VGen-XL: High-Quality Image-to-Video Synthesis via Cascaded Diffusion Models

arXiv.org, 2023
Video synthesis has recently made remarkable strides benefiting from the rapid development of diffusion models. However, it still encounters challenges in terms of semantic accuracy, clarity and spatio-temporal continuity.

Ultra-high precision silicon isotope micro-analysis using a Cameca IMS-1280 SIMS instrument by eliminating the topography effect

Journal of Analytical Atomic Spectrometry, 2019
During very high precision analyses using SIMS, sample surface flatness is one of the major factors in degradation of external analytical repeatability. An additional correction using a secondary ion beam centering parameter (DTCA-X) was used to minimize

Deciphering the physical mechanism of the topography effect for oxygen isotope measurements using a Cameca IMS-1280 SIMS

, 2015
The surface condition of a sample mount is an important factor influencing the precision of SIMS isotope analysis. The phenomenon that the sample topography affects the analytical precision is called the topography effect.

Precise U–Pb zircon dating at a scale of <5 micron by the CAMECA 1280 SIMS using a Gaussian illumination probe

, 2011
Zircon is arguably the best, certainly the most commonly used mineral for U–Pb geochronology. Modern large-geometry secondary ion mass spectrometry (SIMS) has been routinely utilized for precise U–Pb zircon age determination at a lateral resolution of 10–

EventSTR: A Benchmark Dataset and Baselines for Event Stream based Scene Text Recognition

arXiv.org
Mainstream Scene Text Recognition (STR) algorithms are developed based on RGB cameras which are sensitive to challenging factors such as low illumination, motion blur, and cluttered backgrounds. In this paper, we propose to recognize the scene text using
