A biomechanical model for concomitant functioning of neck and shoulder: a pilot study.

A combination of pain syndromes in the neck and shoulder joints creates a significant burden on the healthcare system and has important social and economic significance. Treatment of these pathologies is often inefficient and can reduce the quality of life for patients. Studying of the relationship between pathological changes in the cervical spine and diseases of the shoulder area is crucial for developing more efficient treatment methods.

Photoredox Activation of Fluorinated Organozinc Reagents: Hydrofluoroalkylation of Unactivated and Electron Deficient Alkenes.

Hydrofluoroalkylation of alkenes with organozinc reagents under photocatalytic conditions is described. The fluorinated alkyl radicals were generated from organozincs by the single electron oxidation of the carbon-zinc bond. The radical addition step is followed either by hydrogen atom transfer for unactivated olefins or by a reduction/protonation sequence for strongly accepting arylidenemalononitriles.

The Profile of Network Spontaneous Activity and Functional Organization Interplay in Hierarchically Connected Modular Neural Networks In Vitro.

Modern microtechnology methods are widely used to create neural networks on a chip with a connection architecture demonstrating properties of modularity and hierarchy similar to brain networks. Such in vitro networks serve as a valuable model for studying the interplay of functional architecture within modules, their activity, and the effectiveness of inter-module interaction. In this study, we use a two-chamber microfluidic platform to investigate functional connectivity and global activity in hierarchically connected modular neural networks.

Microfluidic Bi-Layer Platform to Study Functional Interaction between Co-Cultured Neural Networks with Unidirectional Synaptic Connectivity.

The complex synaptic connectivity architecture of neuronal networks underlies cognition and brain function. However, studying the spiking activity propagation and processing in heterogeneous networks in vivo poses significant challenges. In this study, we present a novel two-layer PDMS chip that facilitates the culturing and examination of the functional interaction of two interconnected neural networks.

DT-RRNS: Routing Protocol Design for Secure and Reliable Distributed Smart Sensors Communication Systems.

A smart city has a complex hierarchical communication system with various components. It must meet the requirements of fast connection, reliability, and security without data compromise. Internet of Things technology is widely used to provide connectivity and control solutions for smart sensors and other devices using heterogeneous networking technologies.
