Younger Dryas
The Younger Dryas (around 12,900 to 11,700 years BP) was a return to glacial conditions after the Late Glacial Interstadial, which temporarily reversed the gradual climatic warming after the Last Glacial Maximum (LGM) started receding around 20,000 BP. It is named after an indicator genus, the alpine-tundra wildflower Dryas octopetala, as its leaves are occasionally abundant in late glacial, often minerogenic-rich sediments, such as the lake sediments of Scandinavia. Physical evidence of a sharp decline in temperature over most of the Northern Hemisphere has been discovered by geological research. This temperature change occurred at the end of what the earth sciences refer to as the Pleistocene epoch and immediately before the current, warmer Holocene epoch. In archaeology, this time frame coincides with the final stages of the Upper Paleolithic in many areas. The Younger Dryas was the most recent and longest of several interruptions to the gradual warming of the Earth's climate since the severe LGM, about 27,000 to 24,000 years BP. The change was relatively sudden, taking place in decades, and it resulted in a decline of temperatures in Greenland by 4 to 10°C (7.2 to 18°F) and advances of glaciers and drier conditions, over much of the temperate Northern Hemisphere. It is thought to have been caused by a decline in the strength of the Atlantic meridional overturning circulation, which transports warm water from the Equator towards the North Pole, in turn thought to have been caused by an influx of fresh, cold water from North America to the Atlantic. The Younger Dryas was a period of climatic change, but the effects were complex and variable. In the Southern Hemisphere and some areas of the Northern Hemisphere, such as southeastern North America, a slight warming occurred.

Young Hegelians
The Young Hegelians (German: Junghegelianer), or Left Hegelians (Linkshegelianer), or the Hegelian Left (die Hegelsche Linke), were a group of German intellectuals who, in the decade or so after the death of Georg Wilhelm Friedrich Hegel in 1831, reacted to and wrote about his ambiguous legacy. The Young Hegelians drew on his idea that the purpose and promise of history was the total negation of everything conducive to restricting freedom and reason; and they proceeded to mount radical critiques, first of religion and then of the Prussian political system. They rejected anti-utopian aspects of his thought that "Old Hegelians" have interpreted to mean that the world has already essentially reached perfection.

Young Employees’ Perceptions about Employability Skills for E-Commerce
With the digital transformation of businesses, digital marketing has been a prominent feature of organizations in the 21st century. Changing consumer behavior has also created a need for versatile hard and soft skills for marketing professionals. Given the dynamic growth of the e-commerce market and the trends mentioned above, it is expected that the needs of the labor market will also change. University education aims to develop key competences. Understanding which competences are considered important could improve the motivation of students.

You're Either with Us, or Against Us
In political communication, the phrase "you're either with us, or against us" and similar variations are used to depict situations as being polarized and to force witnesses, bystanders, or others unaligned with some form of pre-existing conflict to either become allies of the speaking party or lose favor. The implied consequence of not joining the team effort is to be deemed an enemy. An example is the statement of the former US President George W. Bush, who said after 9/11 at the launch of his anti-terrorism campaign in the form "Every nation, in every region, now has a decision to make. Either you are with us, or you are with the terrorists."

YOLOv5-AC
Attention Mechanism-Based Lightweight YOLOv5 for Track Pedestrian Detection. In response to the dangerous behavior of pedestrians roaming freely on unsupervised train tracks, the real-time detection of pedestrians is urgently required to ensure the safety of trains and people. Aiming to improve the low accuracy of railway pedestrian detection, the high missed-detection rate of target pedestrians, and the poor retention of non-redundant boxes, YOLOv5 is adopted as the baseline to improve the effectiveness of pedestrian detection by model pruning, improving attention mechanism, etc.

YOLO-Based Unmanned Aerial Vehicle Technology
YOLO-based unmanned aerial vehicle (UAV) technology is proposed in the context of interdisciplinary or multi-disciplinary collaborative research, by the cross-fertilization of You Only Look Once (YOLO) target detection algorithms and UAV technology. In this YOLO-based UAV technology, the UAV can provide more application scenarios for the YOLO algorithm, while the YOLO algorithm can assist the UAV with more novel tasks. The two can complement each other to further facilitate people's daily lives while contributing to the productivity of their respective industries.

Yola (Language)
Yola, historically the Forth and Bargy dialect, is a revived Anglic language once spoken in the baronies of Forth and Bargy in County Wexford, Ireland. It is thought to have evolved from Middle English, which was brought to Ireland during the Norman invasion, beginning in 1169. As such, it was similar to the Fingallian dialect of the Fingal area. Both became functionally extinct in the 19th century, when they were replaced by modern Hiberno-English, although Yola was not officially extinct until the death of the last speaker, a local fisherman of Kilmore Quay named Jack Devereux in 1998. The name "Yola" means "old" in the language.
