Association between air quality index and effects on emergency department visits for acute respiratory and cardiovascular diseases.

open access: yesPLoS ONE, 2023
Background and objectiveSeveral studies suggest that air pollution, particularly PM2.5, increases morbidity and mortality, Emergency Department (ED) visits, and hospitalizations for acute respiratory and cardiovascular diseases.

Realtime Profiling of Fine-Grained Air Quality Index Distribution using UAV Sensing

open access: yes, 2017
Given significant air pollution problems, air quality index (AQI) monitoring has recently received increasing attention. In this paper, we design a mobile AQI monitoring system boarded on unmanned-aerial-vehicles (UAVs), called ARMS, to efficiently build

Engagement With Air Quality Information: Stated Versus Revealed Preferences [PDF]

open access: yes, 2021
Air pollution has a significant impact on health but is often invisible to the naked eye. Real-time air quality information can help people take action to protect their health.

AQI Prediction Based on CEEMDAN-ARMA-LSTM

open access: yesSustainability, 2022
In the context of carbon neutrality and air pollution prevention, it is of great research significance to achieve high-accuracy prediction of the air quality index. In this paper, Beijing is used as the study area; data from January 2014 to December 2019 are used as the training set, and data from January 2020 to December 2021 are used as the test set.

Temperature dependence of spin-cluster resonance intensity in RbFeCl3·2H2O [PDF]

open access: yes, 1983
The spin-cluster resonance intensity is observed as a function of temperature in the pseudo-one-dimensional canted Ising metamagnet RbFeCl3·2H2O. For T 0.7 TN a pure one-dimensional Ising model gives a good description of the observed intensities. For T

Prediction of air quality index based on the SSA-BiLSTM-LightGBM model

open access: yesScientific Reports, 2023
The air quality index (AQI), as an indicator to describe the degree of air pollution and its impact on health, plays an important role in improving the quality of the atmospheric environment.

Resolution correction for surface X-ray diffraction at high beam exit angles [PDF]

open access: yes, 1993
Owing to the two-dimensional periodicity of a superstructure on the crystal surface, the intensity in reciprocal space is continuously distributed along rods normal to the sample surface.

Covariant canonical quantization [PDF]

open access: yes, 2005
We present a manifestly covariant quantization procedure based on the de Donder--Weyl Hamiltonian formulation of classical field theory. This procedure agrees with conventional canonical quantization only if the parameter space is $d=1$ dimensional time.
