An Ultra-wideband Metamaterial Absorber with Angular Stability

Applied Computational Electromagnetics Society Journal (ACES)
In this paper, an ultra-wideband (UWB) microwave absorber with robust angular stability is proposed. Each unit of the structure consists of three-layer stacked resistive films to effectively broaden the absorption bandwidth. A metallic via is inserted in the center of the structure, which effectively guides the TM polarization oblique incident wave ...

Early failure of a locked titanium plate in a proximal humeral fracture: Case report and metallurgic analysis

Trauma Case Reports, 2018
Angular stability locking plates are commonly used in proximal humeral fractures, especially in old patients with osteoporotic bones. These implants show good results in short and midterm follow-up, but complications are not uncommon.

EVALUATION OF ANGULAR INTRAARCH PARAMETERS ON LONGTERM STABILITY

, 2021
AIM: There are still a lot of uncertainties related to long term stability after orthodontic treatment. Mostly, linear measurements were investigated and predictors have not been identified. Aim of this research was to investigate how angular intraarch parameters influence long term stability.

Trunk angular velocity: A convenient, valid and responsive substitute for force plate-based measures of dynamic postural stability.

PLoS ONE
ObjectiveDeficits in dynamic postural stability are associated with increased risk of lower limb injuries. Objective dynamic postural stability assessments typically require force plates, which are not commonly available in the clinic.
