Mechanical Properties of Burnished Steel AISI 1008

Al-Khawarizmi Engineering Journal, 2018
Burnishing improves fatigue strength, surface hardness and decrease surface roughness of metal because this process transforms tensile residual stresses into compressive residual stresses.

A high-speed tunable beam splitter for feed-forward photonic quantum information processing

, 2012
We realize quantum gates for path qubits with a high-speed, polarization-independent and tunable beam splitter. Two electro-optical modulators act in a Mach-Zehnder interferometer as high-speed phase shifters and rapidly tune its splitting ratio. We test

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Electro-chemical grinding [PDF]

, 1972
Electro-chemical grinding technique has rotation speed control, constant feed rates, and contour control. Hypersonic engine parts of nickel alloys can be almost 100% machined, keeping tool pressure at virtual zero.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Influence of Feed Speed and Cutting Depth During Planing on Surface Roughness of Fir, Poplar and Beech Wood

Drvna Industrija
The roughness of the machined surface is a crucial factor in the woodworking process because it influences the quality of future operations like gluing, sanding, pressing, surface treatment and protection, and assembly.

Study on the relationship between material removal rate and tool flank temperature in orthogonal turn-milling

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
Tool flank temperature at various intervals after cutting ISO C45 steel through dry turn-milling is measured using a two-color pyrometer with an optical fiber in order to investigate the cutting characteristics.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
