Killer whales in the Gulf of California are repeatedly attacking juvenile great white sharks, flipping them upside down to ...

Abstract: Magnetic springs using permanent magnets (PMs) have shown advantages in various fields. For instance, they are integrated into precision positioning actuators for passive gravity ...

In the southern Lebanese village of Habboush, the sound that cut through the stillness of the night was not an air strike. It was the sound of a child screaming for help. Hashem, a paramedic in the ...

Capacitive displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.

A three-dimensional finite element model used to simulate the bolted joint is created using ABAQUS package. The stress concentration factors at the roots of the thread are first studied with a preload ...

Abstract: Continuous wave (CW) Doppler radar is a highly sensitive sensor widely used for measuring micromotions of workpieces, blade tip clearance (BTC), and monitoring human vital signs. However, ...

Microelectromechanical systems (MEMS) are pivotal in diverse fields such as telecommunications, healthcare, and aerospace. A critical challenge in MEMS devices is accurately determining the pull-in ...

Scientists believe the shape of the penis may have evolved to help men remove the semen of love rivals during sex. Tests led a team of US researchers, headed by Professor Gordon Gallup, to conclude ...

Israel’s war conduct in Gaza “is consistent with the characteristics of genocide,” including mass civilian casualties and using starvation as a weapon, according to a new United Nations Special ...

The Israeli government is using starvation of civilians as a method of warfare in the Gaza Strip, which is a war crime. Israeli officials have made public statements expressing their aim to deprive ...

The average pore pressure during oil formation is an important parameter for measuring the energy required for the oil formation and the capacity of injection–production wells. In past studies, the ...
