The Generalization of the Stalling’s Theorem [PDF]

open access: yesJournal of Generalized Lie Theory and Applications, 2016
In this paper, we present a relative version of the concept of lower marginal series and give some isomorphisms among i–G-marginal factor groups. Also, we conclude a generalized version of the Stalling’s theorem. Finally, we present a sufficient condition under which the order of the generalized Baer-invariant of a pair of finite groups divides the ...

Comparative study of subsynchronous rotating flow patterns in centrifugal compressors with vaneless diffusers [PDF]

open access: yes, 1982
A comparative experimental investigation of the unstable operating modes of a centrifugal compressor was made. Impeller and/or diffuser rotating stall was observed, depending on the flow conditions.

A Data Driven Review of In Vitro Electrical and Mechanical Stimulation for Post‐Acute Phase Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how in vitro electrical and mechanical stimulation modulates wound healing in fibroblasts and keratinocytes. Analyzing over 560 experimental data points, we relate stimulation parameters to proliferation and migration outcomes, evaluate platform designs, and highlight the need for multi‐parameter optimization to advance targeted ...

Multifunctional Bio‐Based Packaging for Perishable Foods: Structural Design, Scalable Fabrication, and Versatile Applications

open access: yesAdvanced Materials, EarlyView.
An overview of design principles and scalable fabrication strategies for multifunctional bio‐based packaging. Radiative cooling films, modified‐atmosphere films/membranes, active antimicrobial/antioxidant platforms, intelligent optical/electrochemical labels, and superhydrophobic surfaces are co‐engineered from material chemistry to mesoscale structure

Control Surface Freeplay Effects Investigation on Airfoil’s Aero-Elastic Behavior in the Sub-Sonic Regime

open access: yesAerospace, 2019
One of the main limitations of linearity assumptions in airfoil’s aero-elastic problems is the inability to predict the system behavior after starting the instability.

Influence of axial spacing on stall development of FBCDZ-10-No20 mode contra-rotating fan

open access: yesMeitan kexue jishu, 2023
The rotating fan is prone to instability such as stall and even surge when operating at low flow rates. In order to study the influence of axial spacings on the stall inception and its development and propagation process of a contra-rotating fan , a ...

Actuation of Cell Layers in Three Dimensions

open access: yesAdvanced Materials, EarlyView.
ABSTRACT The alignment of fibers and cells in living tissues affect their mechanical properties and functionality. In this context, one can draw an analogy between tissues and nematic liquid crystal elastomers. We explore this analogy by growing fibroblasts on 2D‐patterned substrates and observing the contraction of cell sheets upon detachment from the

Unsteady behavior and mechanism of a rotating stall in a centrifugal compressor with vaneless diffuser

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Unsteady diffuser stall behavior in a centrifugal compressor with a vaneless diffuser was investigated by experimental and computational analyses. The diffuser stall generated as the mass flow rate decreased. The diffuser stall cell rotated at 25-30 % of

A stalled fork stalls recombination

open access: yesThe Journal of Cell Biology, 2005
Homologous recombination does not rescue stalled replication forks during S phase, report Meister et al. on page 537. Rather they find that replication and recombination are separated in terms of when and where they occur. If inappropriate recombination does occur when replication is stalled, replication forks fall apart.Researchers have debated ...

Stall force of a cargo driven by N interacting motor proteins

open access: yes, 2017
We study a generic one-dimensional model for an intracellular cargo driven by N motor proteins against an external applied force. The model includes motor-cargo and motor-motor interactions.
