Automatic rehabilitation assessment method of upper limb motor function based on posture and distribution force.

The clinical rehabilitation assessment methods for hemiplegic upper limb motor function are often subjective, time-consuming, and non-uniform. This study proposes an automatic rehabilitation assessment method for upper limb motor function based on posture and distributed force measurements. Azure Kinect combined with MediaPipe was used to detect upper limb and hand movements, and the array distributed flexible thin film pressure sensor was employed to measure the distributed force of hand.

Improved spatial-temporal graph convolutional networks for upper limb rehabilitation assessment based on precise posture measurement.

After regular rehabilitation training, paralysis sequelae can be significantly reduced in patients with limb movement disorders caused by stroke. Rehabilitation assessment is the basis for the formulation of rehabilitation training programs and the objective standard for evaluating the effectiveness of training. However, the quantitative rehabilitation assessment is still in the experimental stage and has not been put into clinical practice.

Hierarchically porous monoliths based on low-valence transition metal (Cu, Co, Mn) oxides: gelation and phase separation.

Hierarchically porous monoliths based on copper (Cu), cobalt (Co) and manganese (Mn) oxides with three-dimensionally (3D) interconnected macropores and open nanopores were prepared using metal bromides as precursors via a sol-gel process accompanied by phase separation. The difficulty of gelation for low-valence metal cation was overcome by introducing a highly electronegative Br atom near to the metal atom to control the rates of hydrolysis and polycondensation. The 3D interconnected macropores were obtained using appropriate polymers to induce phase separation.

Superelastic Multifunctional Aminosilane-Crosslinked Graphene Aerogels for High Thermal Insulation, Three-Component Separation, and Strain/Pressure-Sensing Arrays.

Aerogels have attracted great interest for their unique properties, but their mechanical brittleness and poor functionality highly limit their practical applications. Herein, we report unprecedented superelastic multifunctional aminosilane-crosslinked reduced graphene oxide (ACrGO) aerogels that are prepared via a facile and scalable strategy involving simultaneous crosslinking and reducing of graphene oxide nanosheets with different kinds of aminosilanes via C-N coupling and hydrolytic polycondensation reactions. It is found that 3-aminopropyl(diethoxy)methylsilane (APDEMS) is the better choice to enhance hydrophobicity, elasticity, and other properties of the resulting aerogels compared with (3-aminopropyl)triethoxysilane.

Frequency dependence of the coercive field of 0.71Pb(MgNb)O-0.29PbTiO single crystal from 0.01 Hz to 5 MHz.

The frequency dependence of the coercive field in [001] poled 0.71Pb(MgNb)O-0.29PbTiO single crystals was investigated as a function of frequency from 0.

A simple and low-cost combustion method to prepare monoclinic VO with superior thermochromic properties.

In this approach, the VO nanoparticles have been successfully fabricated via combusting the low-cost precursor solution consisted of NHVO, CHO and CHOH. By the XRD, TEM and XPS analysis, it can be found that the synthetic monoclinic VO is single crystal and no impurity is defined. After dispersing the VO nanoparticles into the polymer, the solar modulation of VO-based composite film is up to 12.
