We propose a new type of re-writable bitmap image display component using the MEMS (Micro Electro Mechanical Systems) -controlled light scattering. The device is made of a light-guided transparent substrate (glass) and a thin sheet of semi-transparent plastic film (PDMS; Poly Di Methyl Siloxane) with magnetic nickel and light– diffusing glass powders formed in an electrostatic parallel-plate ac...

In an effort to translate PRINT nanoparticle fabrication from batch processes to continuous manufacturing, Liquidia Technologies has harnessed the scale of roll-to-roll processing with the precision of microlithography to enable GMP production of gram to kilogram quantities of nanoparticle based therapeutic formulations. The in-house capabilities now enable fast turnover from single wafer maste...

Abstract We study rapid-turn trajectories in a class of two-field cosmological models, whose scalar manifold is the Poincaré disk. Background solutions multi-field inflation, with field-space exhibiting sharp turns, can seed primordial black hole (PBH) formation. investigate exact hidden symmetry and show that they exhibit kind transient period, needed to induce PBH generation. Furthermore, we ...

We analyse the post-inflationary contribution to stochastic gravitational wave background due a resonant feature in scalar power spectrum, which is characterised by an oscillation log(k), complementing our previous work arXiv:2012.02761 on sharp features. Primordial features signal departures of inflation from single-field slow-roll paradigm and are motivated embeddings high energy physics. fin...

Unusual mechanical properties of mechanical metamaterials are determined by their carefully designed and tightly controlled geometry at the macro- or nanoscale. We introduce a class of nanoscale mechanical metamaterials created by forming continuous corrugated plates out of ultrathin films. Using a periodic three-dimensional architecture characteristic of mechanical metamaterials, we fabricate ...

This paper presents a high-selectivity dual-band bandpass filter with independently-tunable passband frequencies. A tap-coupled structure is utilized to feed the two resonators at lower passband and a coupling structure is used to feed the two resonators at the upper passband. Two pairs of varactor-loaded resonators operating within two different frequency ranges, allow the independent passband...
