Track Segment Association via track graph representation learning

IET Radar, Sonar & Navigation, 2021
Traditional Track Segment Association (TSA) methods used track position vectors or other track information to get association results. However, simply extracting the track position information to form track vectors will lead to the loss of irregular ...

Non-rigid Face Tracking Using Short Track-Life Features [PDF]

2010 International Conference on Digital Image Computing: Techniques and Applications, 2010
We define a “generic” non-rigid face tracker as any system that exhibits robustness to changes in illumination, expression and viewpoint during the tracking of facial land-marks in a video sequence. A popular approach to the problem is to detect/track an ensemble of local features over time whilst enforcing they conform to a global non-rigid shape ...

Charged-Current Disappearance Measurements in the NuMI Off-Axis Beam [PDF]

, 2002
This article studies the potential of combining charged-current disappearance measurements of \nu_{\mu} to \nu_{\tau} from MINOS and an off-axis beam. I find that the error on \Delta m^2 from a 100 kt-yr off-axis measurement is a few percent of itself ...

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]

Fiabilitate şi Durabilitate, 2012
This paper deals with the interaction between a moving wheelset and a slab track due to the short-pitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Measuring Straight Time in Elite Short Track Speed Skating Relays

Procedia Engineering, 2016
AbstractIn short track speed skating, the relay exchange provides an additional strategic component to races by allowing a team to change the skater involved in the pack race. It is thought that during this period of the race, time can be gained or lost due to the execution of the relay exchange. However, the only temporal measurement reported in short

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
