Noncoding RNAs control critical cellular processes, although their contribution to disease remains largely unexplored. Dyskerin associates with hundreds of H/ACA small RNAs to generate a multitude of functionally distinct ribonucleoproteins (RNPs). The DKC1 gene, encoding dyskerin, is mutated in the multisystem disorder X-linked dyskeratosis congenita(More)
A myriad of structurally and functionally diverse noncoding RNAs (ncRNAs) have recently been implicated in numerous human diseases including cancer. Small nucleolar RNAs (snoRNAs), the most abundant group of intron-encoded ncRNAs, are classified into two families (box C/D snoRNAs and box H/ACA snoRNAs) and are required for post-transcriptional modifications(More)
This paper presents a novel uniplanar tunable bandpass filter. In this filter, each resonator can be reconfigured easily using PIN diodes or MEMS switches. Design equations are derived from a simple circuit model which takes into account the multimodal behavior of the coplanar waveguide. Experimental measurements of a 2-GHz prototype, featuring(More)
In this paper, a uniplanar RF-MEMS second-order bandpass filter with reconfigurable centre frequency is presented. It is based on quarter-wavelength slotline resonators and CPW-slotline multimodal immittance inverters (MIIs), which are reconfigured using RF-MEMS switchable CPW air-bridges (SABs). The filter can be adequately explained and designed using(More)
