Effect of prior cold work on the mechanical properties of weldments [PDF]
Heat exchanger units used in steam raising power plant are often manufactured using many metres of austenitic stainless steel tubes that have been plastically formed (bent and swaged) and welded into complex shapes. The amount of plastic deformation (pre-

Time after time – circadian clocks through the lens of oscillator theory
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 Dislocation Mechanics of Crystal/Polycrystal Plasticity
A brief history and update are given in four examples demonstrating that polycrystals are generally stronger than their individual component crystal grains because of obstructed dislocation pile-ups at grain boundaries.

Cyclic elasto-plastic fracture diagram and crack growth life of structures and machine elements [PDF]
The experimental method for the estimation of crack growth resistance of the structure and machine elements under cyclic elasto-plastic straining based on local plastic strain near the crack tip and assuming to receive the complex of the force and ...

Loss of strength in Ni3Al at elevated temperatures [PDF]
Stress decrease above the stress peak temperature (750 K) is studied in h123i single crystals of Ni3(Al, 3 at.% Hf ). Two thermally activated deformation mechanisms are evidenced on the basis of stress relaxation and strain rate change experiments.

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.

Steady states in severe plastic deformations and microstructure at normal and high pressure
The main fundamental problem in studying plasticity and microstructure evolution is that they depend on five components of the plastic strain tensor εp, its entire path εppath, and pressure p and its path ppath, which leaves little hope of finding some ...

In situ observation of deformation processes in nanocrystalline face-centered cubic metals
The atomistic mechanisms active during plastic deformation of nanocrystalline metals are still a subject of controversy. The recently developed approach of combining automated crystal orientation mapping (ACOM) and in situ straining inside a transmission
