Tribological behavior of composite-steel on rolling/sliding contacts for various loads [PDF]

open access: yes, 2011
Composites have replaced metals in the bearing industry for the exclusive performances from its properties were it can accommodate resins, fabrics and additives.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Mathematical modelling of PAF with voltage supply for non-linear loads By GSSA method

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018
This work aims to improve well knowngeneralized averaged models for mathematical modelling of parallel activefilter (PAF) with voltage supply. To achieve this task, the method is adoptedto generalized state space averaging (GSSA) method. Non-linearity of

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Non-Linear Increase of the Real Contact Area of PMMA Blocks and the Related Contact Model

open access: yesChinese Journal of Mechanical Engineering
Many experiments have supported the contact models, such as the GW and MB models, but the majority of previous validations have been performed under light loads, resulting in a linear relationship between normal force and contact area.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Effect of load current harmonics on vibration of three-phase generator

open access: yesMATEC Web of Conferences, 2018
Almost all today electrical loads are considered non-linear such as switch mode power supply (SMPS) for powering computer and mobile phone or variable speed drive (VSD) for driving home and industrial electric motors.

Macroelement modeling of shallow foundations

open access: yes, 2008
The paper presents a new macroelement model for shallow foundations. The model is defined through a non-linear constitutive law written in terms of some generalized force and displacement parameters.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
