Phase One will include an all-abilities destination playground, basketball courts, a dozen new pickleball courts, and a number of other ways to be active and play, but also quieter areas as well.

Hong Kong/London (CNN) — Billionaire Ray Dalio says President Donald Trump’s tariff war has helped push America close to a recession — or perhaps even “something worse.” “Right now ...

DENTON, Texas (KTVT) — Ten University of North Texas students were rescued from a North Texas lake after being flipped from canoes and paddle boards, Texas Game Wardens said Saturday. The ...

Abstract: Cell segmentation in Phase-Contrast (PhC) microscopy is crucial for non-invasive analysis of live-cell imaging data. However, traditional segmentation methods often struggle with challenges ...

Abstract: A new optical condition using an objective lens (OL) of a long focal length (objective mini lens: OM) was tested to enhance image contrast in phase plate transmission electron microscopy ...

The team of researchers, led by Professor Hiromi Miyoshi, came up with a way of tracking cells using phase-contrast microscopy, one of the most common ways of observing cells. Phase-contrast ...

Coupling phase-stable single-cycle terahertz (THz) pulses to scanning tunneling microscope (STM) junctions enables spatiotemporal imaging with femtosecond temporal and Ångstrom spatial resolution. The ...
