Modeling and Design of a Spring-loaded, Cable-driven, Wearable Exoskeleton for the Upper Extremity [PDF]

open access: yes, 2015
An approach to the design of wearable exoskeletons on the basis of simulation of the exoskeleton and a human body model is proposed in this paper. The new approach, addressing the problem of physical human-exoskeleton interactions, models and simulates ...

Ferrous Campylobacter jejuni truncated hemoglobin P displays an extremely high reactivity for cyanide - A comparative study [PDF]

open access: yes, 2008
Campylobacter jejuni hosts two hemoglobins (Hbs). The Camplylobacter jejuni single-domain Hb (called Cgb) is homologous to the globin domain of flavohemoglobin, and it has been proposed to protect the bacterium against nitrosative stress.

Modular simulation software development for liquid propellant rocket engines based on MATLAB Simulink

open access: yesMATEC Web of Conferences, 2017
Focusing on Liquid Propellant Rocket Engine (LPRE) major components, a steady state modular simulation software has been established in MATLAB Simulink. For integrated system analysis, a new algorithm dependant on engine inlet mass flow rate and pressure

Chebyshev super spectral viscosity method for water hammer analysis

open access: yesPropulsion and Power Research, 2013
In this paper, a new fast and efficient algorithm, Chebyshev super spectral viscosity (SSV) method, is introduced to solve the water hammer equations. Compared with standard spectral method, the method's advantage essentially consists in adding a super ...

Random l-colourable structures with a pregeometry

open access: yes, 2012
We study finite $l$-colourable structures with an underlying pregeometry. The probability measure that is used corresponds to a process of generating such structures (with a given underlying pregeometry) by which colours are first randomly assigned to ...

Modeling approach to multi-agent system of human and machine agents: Application in design of early experiments for novel aeronautics systems [PDF]

open access: yes, 2013
Design of future systems for flight-deck automation will reflect a trend of changing the paradigm of human-computer interaction from the master (human)- slave (machine) mode to more equilibrated cooperation.

MATHEMATICAL MODELING OF SELF-OSCILLATIONS IN A LIQUID JET ENGINE DUE TO THE NONSTATIONARY OUTFLOW OF GASES FROM A REACTIVE NOZZLE

open access: yesАвіаційно-космічна техніка та технологія, 2017
The mathematical model of general system instability in a liquid jet engine is obtained, taking into account the nonstationarity of the outflow of combustion products from the jet nozzle. The peculiarity of the variation of self-oscillations of vibration

Mycobacterium tuberculosis LprE Suppresses TLR2-Dependent Cathelicidin and Autophagy Expression to Enhance Bacterial Survival in Macrophages [PDF]

open access: yesThe Journal of Immunology, 2019
Abstract Despite representing a very important class of virulence proteins, the role of lipoproteins in the pathogenesis of Mycobacterium tuberculosis remains elusive. In this study, we investigated the role of putative lipoprotein LprE in the subversion of host immune responses using the M.

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

open access: yesAdvanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

Influence of energy and nutrient supply pre and post partum on performance of multiparous Simmental, Brown Swiss and Holstein cows in early lactation

open access: yesAnimal, 2014
A study was conducted to evaluate the effects of pre partum (PRE) and post partum (POST) dietary energy and nutrient supply (E) and their interactions on feed intake, performance and energy status in dairy cows of three breeds.
