Liang Huang, Liming Dai
AC line-filtering on-chip micro-supercapacitors (MSCs) based on coordination polymer frameworks were fabricated by a facile layer-by-layer method. The reported on-chip MSCs showed a low impedance phase angle of -73° at 120 Hz and a high power density of up to 1323 W cm(-3) with a low relaxation time constant of 0.27 ms.

The purpose of the present study was to investigate the effect of two different resistance training (RT) prescription methods on phase angle (PA) in older women. Seventy-six older women (68.5 ± 5.7 years) were randomly assigned to one of three groups: two training groups that performed an eight-week RT programme either in a constant load (CT, n = 25) or an ascending pyramidal load (PR, n =  26) routine three times per week, or a control group (CG, n =  25) that performed no exercise. The CT programme consisted of three sets of 8-12 repetition maximum (RM) with a constant load for the three sets, whereas the PR training consisted of three sets of 12/10/8 RM with incremental loads for each set...

Accurate evaluation of fracture healing is important for clinical decisions on when to begin weight-bearing and when early intervention is necessary in cases of fracture nonunion. While the stages of healing involving hematoma, cartilage, trabecular bone, and cortical bone have been well characterized histologically, physicians typically track fracture healing by using subjective physical examinations and radiographic techniques that are only able to detect mineralized stages of bone healing. This exposes the need for a quantitative, reliable technique to monitor fracture healing, and particularly to track healing progression during the early stages of repair...

Patients with advanced cancer often experience symptoms of disease and treatment that contribute to distress such as weight loss, which is present in up to 85% of cancer patients. Palliative care in these patients focuses on care aimed at improving quality of life. Phase angle (PA) is obtained by bioelectric impedance analysis (BIA) and is associated with cellular function. It is considered a reliable marker of malnutrition. A low PA may suggest deterioration of the cell membrane, which in palliative patients may result in a short-term survival...

BACKGROUND: The well-known insertion/deletion polymorphism (rs4646994) of the angiotensin-converting enzyme (ACE) gene has been previously associated with obesity, blood flow, muscular strength, and ACE enzyme activity. Despite the relevant role of ACE in homeostasis, few data are currently available on the relationship between rs4646994 and hydration status. Thus, we tested the association between the ACE Ins/Del polymorphism, body composition, and hydration status in a young Italian population...

In the dual-axis rotation inertial navigation system (INS), besides the gyro error, accelerometer error, rolling misalignment angle error, and the gimbal angle error, the shaft swing angle and the axis non-orthogonal angle also affect the attitude accuracy. Through the analysis of the structure, we can see that the shaft swing angle and axis non-orthogonal angle will produce coning errors which cause the fluctuation of the attitude. According to the analysis of the rotation vector, it can be seen that the coning error will generate additional drift velocity along the rotating shaft, which can reduce the navigation precision of the system...
