Binocular vs. monocular 3D cues in multiple object tracking: expertise differences between soccer players and non-athletes.

Classical two-dimensional multiple object tracking (2D-MOT) measures the cognitive ability to track multiple moving elements in real-life-like scenarios. Stereo-three-dimensional MOT (S-3D-MOT), a more ecologically valid form of 2D-MOT, shows better tracking performance in soccer players. Its unique feature is the additional binocular and monocular 3D cues compared to 2D-MOT, but their individual contributions to MOT performance are unclear.

Atmospheric emerging pollutants of cyclic volatile methyl siloxanes across the Yangtze River Delta region revealed by mobile measurements.

Cyclic volatile methyl siloxanes (cVMS) are a large class of high-production-volume chemicals that have garnered increasing scrutiny due to their potential adverse effects on air quality and human health. Among cVMS, octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) dominate global production, with China playing a pivotal role in their manufacture and consumption. Despite their widespread use, the atmospheric occurrence and sources of these compounds in China, even in the Yangtze River Delta (YRD)-the nation's most densely populated and economically developed region-remain largely unknown.

Three-dimensional (3D) stimuli are always better than two-dimensional (2D) multi-tasking? A high cognitive load in 3D-MATB-II.

Objective: The objective of this study is to investigate the whether multi-tasking performance in (three-dimensional) 3D aid or impede cognition compare to (two-dimensional) 2D environments, as reflected by cognitive load. Specifically, we aim to examine the mechanism of multi-tasking under 3D (virtual reality [VR]) and 2D (PC monitor) conditions using the widely used Multi-Attribute Task Battery (MATB) II paradigm.

Methodology: The MATB-II sub-tasks, namely "Tracking" and "System Monitoring," were conducted with varying task demands in both 3D conditions (Tracking Far - System Monitoring Near [TF-SN], Tracking Near - System Monitoring Far [TN-SF]) and a 2D condition with no depth perception (No Depth [ND]).

The Relationship between Football Participation and Sport Trait Confidence for Adolescents: A Chain-Mediated Effect of Collective Self-Esteem and Self-Esteem.

To investigate the relationship between sports participation and sport trait confidence, 1659 teenagers in primary and secondary schools who regularly play football were asked to complete the Sports Participation Scale, Collective Self-Esteem Scale, Self-Esteem Scale, and Sport Trait Confidence Scale. The results show that (1) the positive prediction of football participation on sport trait confidence is not significant; (2) collective self-esteem and self-esteem play a mediating role between football participation and sport trait confidence; (3) the mediating effect occurs through three pathways. The study provides theoretical guidance and empirical evidence for the lead and intervention of adolescent football participation on sport trait confidence.

The role of offensive processes and age development for female soccer players' anticipation.

Anticipation has been confirmed as a more valid measure for recognizing talented athletes than pattern recall alone. Anticipation of offensive processes in soccer, such as counter attacks and positional attacks, is essential for the sport. Additionally, the anticipation of elements such as the soccer ball, offensive and defensive players may also be affected by varied offensive processes.

Two-dimensional and three-dimensional multiple object tracking learning performance in adolescent female soccer players: The role of flow experience reflected by heart rate variability.

Three-dimensional multiple object tracking (3D-MOT) has been used in various fields to mimic real-life tracking, especially in perceptual-cognitive skills training for soccer. Yet, the learning efficiency in 3D-MOT tasks has not been compared with 2D-MOT. Further, whether the advantage can be reflected by heart rate variability (HRV) based on the neurovisceral integration model should also be examined.

Mobile monitoring of VOCs and source identification using two direct-inlet MSs in a large fine and petroleum chemical industrial park.

Mobile monitoring with direct-inlet MS (DI-MS), one of the most direct and effective ways to track emission sources, can effectively serve air quality management in chemical industrial parks (CIPs). Mobile monitoring using a high mass-resolution proton-transfer-reaction time-of-flight MS (HMR-PTR-TOFMS) and single-photon ionization time-of-flight MS (SPI-TOFMS) was conducted in a large fine and petroleum CIP in eastern China for three days. The high mixing ratios of aliphatic hydrocarbons (AHs), aromatics, oxygenated VOCs (OVOCs), and nitrogenous VOCs (NVOCs) were found in the northeast, middle, north, and northeast of the fine chemical industrial zone (FCIZ), respectively.

Stationary monitoring and source apportionment of VOCs in a chemical industrial park by combining rapid direct-inlet MSs with a GC-FID/MS.

Fast and comprehensive monitoring of VOCs, required for air quality management in large-scale chemical industrial parks in China, cannot be accomplished by stationary measurements using conventional GC-FID or GC-MS alone due to their low temporal resolutions and limited detectable ranges. Novel direct-inlet mass spectrometry (DI-MS) has been widely applied for real-time monitoring of VOCs. To verify its applicability in industrial settings, high mass-resolution proton-transfer-reaction time-of-flight MS (HMR-PTR-TOFMS), single-photon ionization time-of-flight MS (SPI-TOFMS), together with online GC-FID/MS were simultaneously deployed at the boundary of one of the largest chemical industrial parks in eastern China.
