Real‐Time Force Monitoring of Electrically Stimulated 3D‐Bioengineered Muscle Bioactuators Using Organic Sensors with Tunable Sensitivity

Advanced Intelligent Systems, EarlyView.
The integration of sensing elements in bioengineered actuators is key to obtain real‐time information about their performance and further control/automation. By coupling flexible organic field‐effect transistor to a skeletal muscle actuator we demonstrate the feasibility to record in real‐time its contractile behavior when stimulated by electrical ...

Mechanisms of intestinal dysbiosis: new insights into tuft cell functions

Gut Microbes
Symbiosis between the host and intestinal microbial communities is essential for human health. Disruption in this symbiosis is linked to gastrointestinal diseases, including inflammatory bowel diseases, as well as extra-gastrointestinal diseases ...

Interaction of rRNA with mRNA and tRNA in Translating Mammalian Ribosome: Functional Implications in Health and Disease

Biomolecules, 2018
RNA-RNA interaction slowly emerges as a critical component for the smooth functioning of gene expression processes, in particular in translation where the central actor is an RNA powered molecular machine.

A Model for One-Dimensional Coherent Synchrotron Radiation including Short-Range Effects [PDF]

arXiv, 2012
A new model is presented for simulating coherent synchrotron radiation (CSR) in one dimension. The method is based on convolving an integrated Green function (IGF) with the longitudinal charge density. Since it is based on an IGF, the accuracy of this approach is determined by how well one resolves the charge density and not by resolving the single ...

Sensor‐Embedded Muscle for Closed‐Loop Controllable Actuation in Proprioceptive Biohybrid Robots

Advanced Intelligent Systems, EarlyView.
Skeletal muscle tissue‐based bioactuators move in response to externally applied electrical stimuli in open‐loop control, which lacks knowledge of the actuator's state. Herein, a soft and fiber‐shaped piezoresistive mechanosensor that integrates with the soft tissue and operates in the cell culture environment is used to create the first proprioceptive

An elasto-visco-plastic model for immortal foams or emulsions [PDF]

, 2007
A variety of complex fluids consist in soft, round objects (foams, emulsions, assemblies of copolymer micelles or of multilamellar vesicles -- also known as onions). Their dense packing induces a slight deviation from their prefered circular or spherical shape.

Tackling Inter- and Transdisciplinary Challenges: A New Research Approach for the Institute for Interdisciplinary Mountain Research

Mountain Research and Development
Mountain areas are defined by their high relief energy, dynamic nature, and diverse geo-, hydro-, eco-, and anthroposystems. They are significantly affected by climate change and globalization, presenting complex research challenges from local to global ...

Spin-Fermion Model of Magnetism: Quasi-particle Many-Body Dynamics [PDF]

arXiv, 2004
Theoretical foundations and applications of the generalized spin-fermion (sp-d) exchange lattice model to various magnetic systems, e.g. rare-earth metals and compounds and magnetic semiconductors are discussed. The capabilities of the model to describe spin quasi-particle spectra are investigated. The main emphasis is made on the dynamical behavior of

Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection

Animal Models and Experimental Medicine, EarlyView.
This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic
