Sustainable machining: process energy optimisation of wire electrodischarge machining of Inconel and titanium superalloys [PDF]

open access: yes, 2017
Process energy optimisation is vital in view of the environmental performance of electrodischarge machining (EDM). This research is focused on identifying the significant parameters that optimise the process energy consumption of wire EDM (WEDM) of ...

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

open access: yesFEBS 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

open access: yesFEBS 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 ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Sustainable Drilling Strategies for Rivet Hole Formation in Nickel-Based Alloys for Aeronautical Applications

open access: yesJournal of Manufacturing and Materials Processing
The formation of rivet holes is a critical step in aeronautical assembly, as hole quality directly influences the fatigue resistance and structural reliability of riveted joints. Nickel-based alloys, such as Inconel 625, present additional challenges due

Dry sliding friction and wear response of WC-Co hardmetal pairs in linearly reciprocating and rotating contact [PDF]

open access: yes, 2011
This paper presents an experimental evaluation of friction and wear properties of WC-Co cemented carbides. A comparison is made between unlubricated rotating and linearly reciprocating pin-onplate sliding pairs. The plate specimens were WC-10wt%Co grades
