Setting up the physical principles of resilience in a model of the Earth System [PDF]

open access: yesEarth System Dynamics
Resilience is a property of social, ecological, social-ecological and biophysical systems. It describes the capacity of a system to cope with, adapt to and innovate in response to a changing surrounding.

A review of numerical analysis of friction stir welding

open access: yes, 2014
Friction stir welding is a relatively new solid-state joining technique which is widely adopted in different industry fields to join different metallic alloys that are hard to weld by conventional fusion welding. Friction stir welding is a highly complex

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

DataSheet1_Negative or Positive? Loading Area Dependent Correlation Between Friction and Normal Load in Structural Superlubricity.docx

open access: yes, 2022
Structural superlubricity (SSL), a state of ultra-low friction between two solid contacts, is a fascinating phenomenon in modern tribology. With extensive molecular dynamics simulations, for systems showing SSL, here we discover two different dependences

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Response of Dust Occurrences to Global Warming in Northeastern Iran Using MAIAC Satellite Observations and CMIP6-HighResMIP Simulations [PDF]

open access: yesمحیط شناسی
Objective: Northeastern Iran is acutely vulnerable to environmental hazards, a vulnerability largely driven by persistent droughts and widespread land-use changes. Despite this deep-seated ecological sensitivity, the development of robust risk management

Dissipation of vibration in rough contact [PDF]

open access: yes, 2010
The relationship which links the normal vibration occurring during the sliding of rough surfaces and the nominal contact area is investigated. Two regimes are found.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Break-Out Resistance of Offshore Pipelines Buried in Inclined Sandy Seabed

open access: yesJournal of Marine Science and Engineering
Submarine pipelines are highly susceptible to lateral buckling failure under service conditions of high temperature and pressure. While existing bearing capacity evaluation methods mainly focus on flat seabeds, research on the ultimate bearing capacity ...
