The Trajectory of a Particle. Inertial Classification.

Journal of the Society of Powder Technology, Japan, 1991
The objective of inertial classification facilities is to classify the particles which follow the flow well and particles which do not. The flow in which the vertical flowing direction is slightly bent to the right side, and thereafter, largely bent to the left side is taken up.

Underwater Low-speed Small Targets Classification Using Highlights and Trajectory Features

水下无人系统学报
Traditional statistical learning methods rely only on manually designed trajectory features with single feature representation and limited classification performance in the classification task of underwater low-speed small targets. To address this issue,

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.

Improving trajectory classification through Kramers–Moyal coefficients

AI Open
Trajectory classification focuses on predicting the class or category of a moving object based on its observed movement over time. The classification of trajectory data using classical approaches can be challenging due to the arbitrary and relatively ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Motion Classification Based on Geometrical Features of Trajectories

2024 IEEE International Symposium on Biomedical Imaging (ISBI)
This paper proposes a novel approach for motion clas-sification based on geometrical features computed on tra-jectories. The method follows a machine learning approachtrained and validated on synthetic datasets simulating severalstochastic models. The resulting model enables, in particular,the recognition of different subdiffusive behaviors, offering ...

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

Aging 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 ...
