HF pump-induced electron heating and artificial airglow at high latitudes: Aspect angle dependence [PDF]

open access: yes, 2002
Large electron temperature increases (~3000 K) in the ionospheric F-region, produced by powerful HF wave injection, were measured using the EISCAT incoherent scatter radar near Tromsø, Norway, on 7 October 1999.

Persistent enhancement of the HF pump-induced plasma line measured with a UHF diagnostic radar at HAARP [PDF]

open access: yes, 2006
Plasma lines excited by a powerful, high-frequency (HF) radio wave are studied using data obtained with an ultrahigh frequency (UHF) radar at HAARP (High Frequency Active Auroral Research Program) from 3 to 5 February 2005.

lncRNA2919 Suppresses Rabbit Dermal Papilla Cell Proliferation via trans-Regulatory Actions

open access: yesCells, 2022
Hair follicles (HFs) are complex organs that grow cyclically during mammals’ growth and development. Long non-coding RNAs (lncRNAs) cannot be translated into proteins and play crucial roles in many biological processes.

An Exploration of Heart Failure Risk in Breast Cancer Patients Receiving Anthracyclines with or without Trastuzumab in Thailand: A Retrospective Study

open access: yesClinics and Practice, 2021
Anthracycline-based regimens with or without anti-human epidermal growth factor receptor (HER) 2 agents such as trastuzumab are effective in breast cancer treatment. Nevertheless, heart failure (HF) has become a significant side effect of these regimens.

THE PROBABILITY DETERMINATION OF ERROR-FREE AIR TRAFFIC CONTROLLER OPERATION

open access: yesНаучный вестник МГТУ ГА, 2018
Human error is considered to be a cause or one of the main factors in most accidents. Errors are not a certain type of deviation in behaviour; they are a natural product of all human efforts.

Ionospheric electron heating, optical emissions, and striations induced by powerful HF radio waves at high latitudes: Aspect angle dependence [PDF]

open access: yes, 2003
In recent years, large electron temperature increases of 300% (3000 K above background) caused by powerful HF-radio wave injection have been observed during nighttime using the EISCAT incoherent scatter radar near Tromsø in northern Norway.

Strategies to Modify the Risk of Heart Failure Readmission

open access: yesHealth Services Research & Managerial Epidemiology, 2017
Background: Human factors play an important role in health-care outcomes of heart failure (HF) patients. A systematic review and meta-analysis of clinical trial studies on HF hospitalization may yield positive proofs of the beneficial effect of specific ...

Effect of C-reactive protein on the risk of Heart failure: a mendelian randomization study

open access: yesBMC Cardiovascular Disorders, 2023
Background Traditional observational studies have shown positive associations between c-reactive protein (CRP) and heart failure (HF) risk. However, this association has not been fully elucidated.

Genetic polymorphism of human factor H (HF,β1H globulin) in Chinese han population in northeast China [PDF]

open access: yesJapanese journal of human genetics, 1992
The distribution of human factor H of serum phenotypes were studied using ultrathin polyacrylamide gel isoelectric focusing (PAGIEF) and subsequent immunoblotting techniques in 203 Chinese of Han population in Liaoning Province of northeast China. The gene frequencies of HF*A and HF*B were 0.4828 and 0.5172, respectively.
