Influence of Cutting Angle on Temperature Distribution of Cutter

Shiyou jixie, 2021
The failure of cutter is closely related to cutting temperature, and the formation of cuttings has an impact on the performance and life of cutter. This article builds a rock-breaking mechanics model to conduct numerical simulation analysis on rock ...

Influence of cutting fluid on tool edge temperature in end milling titanium alloy

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This study investigates the influence of cutting fluid on the cutting temperature in end milling of a titanium alloy. As the cutting temperature, the tool edge temperature was measured using a two-color pyrometer with an optical fiber.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Strong gate coupling of high-Q nanomechanical resonators

, 2010
The detection of mechanical vibrations near the quantum limit is a formidable challenge since the displacement becomes vanishingly small when the number of phonon quanta tends towards zero.

Finite-temperature reaction-rate formula: Finite volume system, detailed balance, $T \to 0$ limit, and cutting rules [PDF]

, 1997
A complete derivation, from first principles, of the reaction-rate formula for a generic process taking place in a heat bath of finite volume is given. It is shown that the formula involves no finite-volume correction.
