Non-targeted Tracer Fate Detection [PDF]
, 2015 Stable isotopes have been used to trace atoms through metabolism and quantify metabolic fluxes for several decades. Only recently non-targeted stable isotope labeling approaches have emerged as a powerful tool to gain insights into metabolism. However, the manual detection of isotopic enrichment for a non-targeted analysis is tedious and time consuming.

Target-adaptive Graph for Cross-target Stance Detection [PDF]
Proceedings of the Web Conference 2021, 2021 Target plays an essential role in stance detection of an opinionated review/claim, since the stance expressed in the text often depends on the target. In practice, we need to deal with targets unseen in the annotated training data. As such, detecting stance for an unknown or unseen target is an important research problem.

A bottom–up model of spatial attention predicts human error patterns in rapid scene recognition [PDF]
, 2007 Humans demonstrate a peculiar ability to detect complex targets in rapidly presented natural scenes. Recent studies suggest that (nearly) no focal attention is required for overall performance in such tasks.

Multichannel direct detection of light dark matter: Target comparison [PDF]
, 2020 Direct-detection experiments for light dark matter are making enormous leaps in reaching previously unexplored model space. Several recent proposals rely on collective excitations, where the experimental sensitivity is highly dependent on detailed ...

Nuclear target effect on dark matter detection rate [PDF]
, 2005 Expected event rates for a number of dark matter nuclear targets were calculated in the effective low-energy minimal supersymmetric standard model, provided the lightest neutralino is the dark matter Weakly Interacting Massive Particle (WIMP).

Research on Multi-Ship Target Detection and Tracking Method Based on Camera in Complex Scenes
Journal of Marine Science and Engineering, 2022 Aiming at the problem that multi-ship target detection and tracking based on cameras is difficult to meet the accuracy and speed requirements at the same time in some complex scenes, an improved YOLOv4 algorithm is proposed, which simplified the network ...

Shifting attention in viewer- and object-based reference frames after unilateral brain injury [PDF]
, 2011 The aims of the present study were to investigate the respective roles that object- and viewer-based reference frames play in reorienting visual attention, and to assess their influence after unilateral brain injury.
