Downward nominal and real wage rigidity : Survey evidence from European firms [PDF]

open access: yes
It has been well established that the wages of individual workers react little, especially downwards, to shocks that hit their employer. This paper presents new evidence from a unique survey of firms across Europe on the prevalence of downward wage ...

Simulation models of vibrations at holes boring factored in the technological system’s variable rigidity

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2014
At elongated holes boring several imperfections can occur, namely, the surface waviness and shape inaccuracies in the axial section. This research purpose is to establish the regularities of such imperfections formation depending on the technological ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Naringenin nanoliposomes alleviate hyperuricemia by inhibiting NLRP3 inflammasome: effects of rigidity

open access: yesFood Science and Human Wellness
Hyperuricemia (HUA) is a metabolic disease characterized by high levels of uric acid (UA) in the blood and varying degrees of kidney damage. Desirable nanoliposomes should simultaneously exhibit efficient biocompatibility and effective drug delivery ...

CORONA RIGIDITY

open access: yesThe Bulletin of Symbolic Logic
Abstract We give a unified overview of the study of the effects of additional set theoretic axioms on quotient structures. Our focus is on rigidity, measured in terms of existence (or rather non-existence) of suitably non-trivial automorphisms of the quotients in question. A

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Torsional vibration analysis of the surface‐mounted permanent magnet synchronous machine using analytical model considering flux harmonics

open access: yesIET Electric Power Applications, 2021
The torsional vibration of the surface‐mounted permanent magnet synchronous machine (SPMSM) caused by torque ripple is analysed herein. First, an improved mathematic model of the SPMSM accounting for torsional vibration effect is proposed, which is ...
