Modeling and validation of residual stress in a metallic wall manufactured by direct energy deposition: a numerical and experimental study

Scientific Reports
Residual stresses have been identified as one of the biggest challenges in each Directed Energy Deposition process (DED). Residual stresses can significantly affect the dimensional accuracy, mechanical performance, and service life of additively ...

Distribution and formation mechanism of residual stress in duplex stainless steel weld joint by neutron diffraction and electron backscatter diffraction

Materials & Design, 2019
The residual stress distribution of duplex stainless steel multi-pass weld joint and its formation mechanism still lacks systematic research. In this study, neutron diffraction and electron backscatter diffraction were used to systematically investigate ...

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

FEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Assessment of residual stress using thermoelastic stress analysis

, 2011
The work described in this thesis considers the application of thermoelastic stress analysis (TSA) to theassessment of residual stresses in metallic materials. Residual stresses exist within almost all engineeringcomponents and structures.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Predicting fatigue crack growth life for cold-worked holes based on existing closed-form residual stress models. [PDF]

, 2003
This paper studies the capability of four closed-form solutions for calculating cold expansion-induced residual stresses. The aim is to check whether these models are able to provide accurate solutions of residual stresses for three aerospace grade ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Comparison of joining efficiency and residual stresses in laser and laser hybrid welding [PDF]

, 2011
Laser welding is a high energy density process, which can produce welds with less energy input and thereby lower residual stress generation compared to arc welding processes.
