Effect of MQL in high speed end-milling of Ti-6Al-4V with PVD coated tools
Nihon Kikai Gakkai ronbunshu, 2016 The high speed milling of Ti-6A-4V was investigated in order to clarify the efficiency of MQL and PVD coated tool. Cutting speed was very high 200m/min. TiAlN, TiCN, TiN, DLC and non-coated tools were used. Cooling methods were dry, wet and MQL (15mL/h).

Machining performance of vegetable oil with phosphonium- and ammonium-based ionic liquids via MQL technique [PDF]
, 2019 Thermo-mechanical loads are the main factor that influences the tool wear and product surfaces during machining processes. Lubrication in metal cutting is an effective medium to reduce frictional forces and wear on the tool-workpiece interfaces.

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.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
