Transparent electromagnetic interference (EMI) shielding is needed in many optoelectronic applications to protect electronic devices from surrounding radiation while allowing for high visible light transmission. However, very high transmission (over 92.5%), high EMI shielding efficiency (over 30 dB) structures have yet to be achieved in the literature.

Geometrically, the disk expands to a cone shape that is asymmetric about the mid-plane. In this paper, we describe how secular gravitational torques between individual orbits drive this "inclination instability".

The non-finite reason clause has an understood subject, PRO, that is anaphoric; here it may be understood as naming the agent of the event of the host clause. Yet since the host is a short passive, this agent is realized by no audible dependent.

Management consists of eradication of the infection and either, revision of the initial surgery or some form of salvage procedure. There are instances however when the patient is asymptomatic, medically unfit, or the local tissue is too tenuous to warrant performing additional surgery.

The first 97 cases were assessed throughout the year at 6 weeks and 3, 6, and 12 months. Data were extracted through retrospective chart review, operative reports, and electronic goniometry of the implant in maximal dorsiflexion and plantarflexion.
