Research on Aircraft Turbulence Early Warning Technology Driven by Ensemble Kalman Filter and Multiscale Information

open access: yesJournal of Advanced Transportation
Flight turbulence poses a severe threat to aviation safety, and achieving its effective early warning is a critical challenge to be addressed. To overcome the limitations of traditional methods reliant on single information sources or advanced remote ...

Managing the quality of CPC traffic [PDF]

open access: yesProceedings of the 10th ACM conference on Electronic commerce, 2009
We show how an online advertising network can use filtering, predictive pricing and revenue sharing together to manage the quality of cost-per-click (CPC) traffic. Our results suggest that predictive pricing alone can and should be used instead of filtering to manage organic traffic quality, whereas either method can be used to deter click inflation.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

A Multiaircraft Path Distributive Planning Method via Autonomous Self-Separation Operation Mode

open access: yesJournal of Advanced Transportation
In this paper, a multiaircraft path planning method framework for autonomous operation and distributed decision-making was proposed. The core content of this framework consists of two parts: single-aircraft path planning and multiaircraft path ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Identifying key nodes in complex networks based on an improved gravity model

open access: yesFrontiers in Physics, 2023
The identification of key nodes in complex networks is a hot topic. Therefore, it attracts increasing attention from different fields, like airline networks and social networks. To identify the key nodes in complex network, we suggest an improved gravity

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Diabetes‐Associated Cognitive Impairment: Pathophysiology and Emerging Therapies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diabetes‐associated cognitive impairment (DACI) is a common yet underrecognized condition, manifesting along a spectrum from mild cognitive impairment to dementia. DACI encompasses patients who develop vascular dementia (VaD) or Alzheimer's disease (AD) with diabetes as a risk factor; however, in certain patients, particularly those lacking ...
