A novel piezoelectric actuator using a two-stage Legionnaires Hats flexure hinge structure is proposed in this paper, which is used in a compact and high-precision electromechanical field.The two-stage flexure hinge structure is used to provide horizontal thrust and vertical clamping force to the driving feet, which solves the problems of unstable
Struma ovarii is a rare ovarian teratoma of monodermal variant constituting 1-4% of all benign Baby Bubble Baths ovarian teratoma.Any ovarian teratoma is called struma ovarii only when it consists of at least 50% thyroid tissue.Only about 8% of struma ovarii cases present with clinical and biochemical features of thyrotoxicosis which is presumed to
Attention-deficit/hyperactivity disorder (ADHD) is a syndrome characterized by impaired attention, impulsivity and hyperactivity in children.These symptoms are often maintained in adults.During adolescence, prefrontal cortex develops connectivity with other brain regions to engage executive functions such as, latent inhibition, attention and inhibi
Oropharyngeal candidiasis (OPC) is the most common human fungal infection, arising typically from T cell immune impairments.IL-17 and IL-22 contribute individually to OPC responses, but here we demonstrate that the combined actions of both cytokines RTF are essential for resistance to OPC.Mice lacking IL-17RA and IL-22RA1 exhibited high fungal load
This paper presents non-contact vital sign monitoring in neonates, based on image processing, where a standard color camera captures the plethysmographic signal and the heart and breathing rates are processed and estimated online.It is important that the measurements are taken in a non-invasive manner, which is imperceptible to the patient.Currentl
