Isolated thunderstorms are possible for Saturday afternoon. Continuous westerly winds will converge with the Atlantic sea breeze and lead to storms. Convection will also cause secondary storms ...

Daytime heating could fuel redevelopment of a few isolated showers this afternoon and evening, but most of the area is expected to remain dry. Lows tonight fall into the upper 50s and low 60s as ...

So overnight tonight, partly cloudy skies. It may be an isolated shower as some of that out to the west tries to get in here, but most of us aren't gonna see anything out of it. 62 to 68 for your ...

which allows the calculation of the scattering and penetration of isolated vegetation specimens such as, e.g., single trees, bushes, etc., at mm-wave frequencies. For this purpose, the RTE is stated ...

Abstract: A comprehensive time-domain model of a CLLC class isolated bidirectional dc-dc converter (IBDC) is proposed in this article. Based on the circuit analysis and the solution of the state ...

President Donald Trump reacted on Monday for the first time since an Egyptian national allegedly threw Molotov cocktails into a crowd of pro-Israel protesters in Boulder, Colorado, injuring eight ...

Garbage may be back in action with their newly-released eighth studio album, Let All That We Imagine Be the Light, but vocalist Shirley Manson admits that not everything in the band is "hunky dory", ...

A study published in Nature Communications presents a way to create deployable structures that transform from compact folded states into expansive configurations with perfectly smooth surfaces.

To this end, structure and structure-property relations of melts and coexisting fluids in silicate-COH systems have been determined at temperatures up to 1000 degrees C and at pressures to similar to ...

For this reason, we have also investigated seventeen bacterial isolates for their carbonate and silicate dissolution potential ... As the bacterial isolates were isolated from yogurt samples, they ...
